1. Which word is closest in meaning to EXPEDITE?
- A. Postpone
- B. Speed up
- C. Record
- D. Question
Ver respuesta y explicación
Respuesta: B. Speed up
To expedite something is to make it happen faster. The word comes from Latin roots meaning to free the feet, so the picture behind it is clearing an obstacle out of the way. Vocabulary items usually offer one near opposite, here postpone, because a test taker who half remembers the word tends to grab it.
2. Which sentence is written correctly?
- A. The list of applicants were sent to the hiring office.
- B. The list of applicants have been sent to the hiring office.
- C. The list of applicants was sent to the hiring office.
- D. The lists of applicants was sent to the hiring office.
Ver respuesta y explicación
Respuesta: C. The list of applicants was sent to the hiring office.
The subject is list, which is singular, so the verb is was. The phrase of applicants sits between the subject and the verb and has no effect on the verb form. Cross out any phrase that starts with a preposition and the agreement gets obvious, which is why the last option is wrong in the opposite direction: lists is plural and needs were.
3. Complete the series.
4, 7, 13, 25, _____, 97
Opciones para el hueco 1: 37, 49, 50, 61
Ver respuesta y explicación
Respuesta: 49
The gaps are 3, 6, 12 and 24, so each gap doubles, which makes the next gap 24 doubled, or 48. Adding 48 to 25 gives 49, and 49 plus 96 gives 97, which confirms the rule. The same series also follows the rule double the number and subtract one, and when two rules both fit, checking them against the last given term settles it.
4. A department received 1,260 applications. One clerk sorted 40 percent of them and the two remaining clerks split the rest evenly. How many did each of those two clerks sort?
- A. 252
- B. 378
- C. 420
- D. 504
Ver respuesta y explicación
Respuesta: B. 378
Forty percent of 1,260 is 504, so 756 are left. Split evenly between two clerks, that is 378 each. The wrong answers are the traps you get by stopping early: 504 is the first clerk's share, and 420 is what you get by splitting all 1,260 three ways and ignoring the percentage.
5. Which of these are standard rules in an alphabetical filing system?
Marca todas las que correspondan.
- A. A personal name is filed by surname first, then given name, then middle name or initial.
- B. Nothing comes before something, so Bell is filed before Bellamy.
- C. A prefix such as De, Van or Mac stays attached to the surname rather than being treated as a separate word.
- D. A title such as Dr. or Captain decides the order when two surnames are identical.
- E. Names written with digits are always filed after every alphabetic name.
Ver respuesta y explicación
Respuesta: A. A personal name is filed by surname first, then given name, then middle name or initial., B. Nothing comes before something, so Bell is filed before Bellamy., C. A prefix such as De, Van or Mac stays attached to the surname rather than being treated as a separate word.
Filing items reward knowing the ordering logic rather than guessing. Names are compared unit by unit, surname first, and a shorter unit sorts before a longer one that starts the same way, which is the nothing before something rule. A prefix is part of the surname, so Van Dyke files under V. Titles are used only as a last resort after every other unit matches, and numeric filing usually comes before alphabetic, not after. Where a specific agency's manual differs, its manual is what the test follows, so read the one you are given.
6. A coding key assigns A=1, B=2, C=3, D=4, E=5. The rule is: shift each letter one position later in the alphabet, then write the number of the new letter. What code does BAD produce?
- A. 325
- B. 214
- C. 132
- D. 436
Ver respuesta y explicación
Respuesta: A. 325
Shift each letter first: B becomes C, A becomes B, D becomes E. Then read the numbers: C is 3, B is 2, E is 5, giving 325. The wrong answer 214 is what you get by skipping the shift and coding the letters as they stand, which is the single most common slip on coding items. Do the steps in the order the rule gives them, one letter at a time.
7. Complete the sentence.
A candidate answers 45 of 60 questions correctly, which is _____ percent. Answering the same share of an 80 question test correctly would mean _____ correct answers.
Opciones para el hueco 1: 66, 70, 75, 80
Opciones para el hueco 2: 55, 60, 65, 70
Ver respuesta y explicación
Respuesta: 75, 60
45 divided by 60 is 0.75, which is 75 percent. Applying that share to 80 questions gives 0.75 times 80, which is 60. Once you have the share as a decimal you can move it onto any total, and that is faster than setting up a new proportion each time. Note that a percentage correct is not the same as a passing score, since each jurisdiction sets its own passing standard.
8. A county office posts this notice: Applications delivered in person are date stamped at the counter. Applications sent by mail are date stamped on the day they are opened, which may be later than the postmark. Applications are reviewed in date stamp order. Based only on the notice, which statement is supported?
- A. An application handed in at the counter can be reviewed before one that was mailed earlier.
- B. A mailed application is reviewed according to its postmark date.
- C. Two applications mailed on the same day are always reviewed together.
- D. Applications delivered in person are reviewed before all mailed applications.
Ver respuesta y explicación
Respuesta: A. An application handed in at the counter can be reviewed before one that was mailed earlier.
The notice says review order follows the date stamp, and that a mailed application is stamped when it is opened, which can be after its postmark. That is enough to support the first statement and it rules out the second. The other two overreach: always and all are stronger than anything the notice says, since a mailed application opened today is stamped the same day as one handed in today. On reading items, answer from the passage alone and be suspicious of absolutes.
9. You are working a public counter. A resident becomes loud and angry after learning the form they filled out was the wrong one. Which of these are appropriate first responses?
Marca todas las que correspondan.
- A. Let the person finish speaking before you start explaining.
- B. Tell them calmly which form is the correct one and what happens next.
- C. Point out that the instructions were posted and they should have read them.
- D. Keep your voice level and stay at the counter unless you feel unsafe.
- E. Walk away and start serving the next person in line.
Ver respuesta y explicación
Respuesta: A. Let the person finish speaking before you start explaining., B. Tell them calmly which form is the correct one and what happens next., D. Keep your voice level and stay at the counter unless you feel unsafe.
Situational judgment items are looking for the response that solves the problem and keeps the situation calm, not the one that assigns blame. Listening first, giving a clear next step and keeping your own tone steady all do that. Telling someone they should have read the instructions is correct and useless at the same time, and walking off leaves the problem unsolved. Keep in mind that the scoring key is written by the hiring agency and reflects how it wants its staff to behave, so read any published values statement for the job you applied to.
10. A square sheet of paper is folded in half, then folded in half again. A single hole is punched through all the layers. When the paper is unfolded, how many holes are there?
- A. Two
- B. Three
- C. Four
- D. Eight
Ver respuesta y explicación
Respuesta: C. Four
Each fold doubles the number of layers. One fold gives two layers, a second fold gives four, and the punch goes through every layer, so unfolding reveals four holes. The rule is that the number of holes equals two multiplied by itself once per fold, so three folds would give eight. Counting layers is the reliable way through paper folding items, and sketching the folds in the margin costs a few seconds and saves the guess.
11. A dispatcher records this description: blue sedan, license plate RTK 4192, traveling north on Third Street. Which report below matches that description exactly?
- A. Blue sedan, plate RTK 4912, northbound on Third Street
- B. Blue coupe, plate RTK 4192, northbound on Third Street
- C. Blue sedan, plate RTK 4192, northbound on Third Avenue
- D. Blue sedan, plate RTK 4192, northbound on Third Street
Ver respuesta y explicación
Respuesta: D. Blue sedan, plate RTK 4192, northbound on Third Street
Only the last option matches on all three details. The others each change exactly one thing: 4912 transposes two digits, coupe changes the body style, and Avenue changes the street type. Observation items are built from single small changes like these, so compare one field at a time, in the same order every time, instead of reading each option as a whole sentence.
12. In each pair below, the same record has been copied from one list to another. Which pairs are exact matches?
Marca todas las que correspondan.
- A. Kowalczyk, Anna 5583041 and Kowalczyk, Anna 5583041
- B. Reyes-Ortega, M. 4471902 and Reyes-Ortega, M. 4471902
- C. Stephenson, Carl 8820376 and Stephenson, Carl 8820736
- D. O'Donnell, Sean 3319548 and ODonnell, Sean 3319548
- E. Whitfield, Dana 6604215 and Whitfield, Diana 6604215
Ver respuesta y explicación
Respuesta: A. Kowalczyk, Anna 5583041 and Kowalczyk, Anna 5583041, B. Reyes-Ortega, M. 4471902 and Reyes-Ortega, M. 4471902
The first two agree character for character. The third transposes 3 and 7 in the middle of the number, the fourth drops the apostrophe, and the fifth turns Dana into Diana. Checking items are scored on accuracy under time pressure, and the reliable method is to split each record into fields and compare them in the same order every time, reading numbers in small groups rather than as one long string.
13. Complete the sentence.
Filing Sanders, Sandburg and Sandoval in strict alphabetical order, the name that comes first is _____ and the name that comes last is _____.
Opciones para el hueco 1: Sanders, Sandburg, Sandoval
Opciones para el hueco 2: Sanders, Sandburg, Sandoval
Ver respuesta y explicación
Respuesta: Sandburg, Sandoval
All three share the first four letters, S, a, n and d, so the fifth letter decides: b in Sandburg, e in Sanders, o in Sandoval. That gives Sandburg, Sanders, Sandoval. Compare letter by letter and stop at the first letter that differs, because judging by how the whole name looks or sounds is what puts Sanders first for most people.
14. Which sentence uses affect and effect correctly?
- A. The new rule will effect how many forms you file, and the affect was immediate.
- B. The new rule will affect how many forms you file, and the effect was immediate.
- C. The new rule will affect how many forms you file, and the affect was immediate.
- D. The new rule will effect how many forms you file, and the effect was immediate.
Ver respuesta y explicación
Respuesta: B. The new rule will affect how many forms you file, and the effect was immediate.
In ordinary use affect is the verb, meaning to influence, and effect is the noun, meaning the result. The rule affects the forms, and the result is the effect. Effect does exist as a verb, meaning to bring about, as in effect a change, but it does not fit here, where the sentence is about influencing something that already exists.
15. Which letter comes next in this series: B, D, G, K, P?
- A. S
- B. T
- C. U
- D. V
Ver respuesta y explicación
Respuesta: D. V
Turn the letters into their positions in the alphabet: 2, 4, 7, 11, 16. The gaps are 2, 3, 4 and 5, so the next gap is 6, giving position 22, which is V. Converting letters to numbers is the standard move on letter series, because a growing gap is nearly invisible in letters and obvious in numbers.
16. A records office processed these numbers of forms this week: Monday 48, Tuesday 52, Wednesday 61, Thursday 39, Friday 45. What is the average number of forms processed per day?
- A. 47
- B. 49
- C. 51
- D. 52
Ver respuesta y explicación
Respuesta: B. 49
Add the five days to get 245 forms, then divide by five days to get 49. The other numbers are traps. 48 is the median, the middle value once the days are put in order, and 52 is the second highest day. When a question asks for an average, add first and divide second, and check that your answer sits between the lowest and the highest value.
17. A clerk enters 36 records in 45 minutes. At the same rate, how many records can the clerk enter in 2 hours?
- A. 80
- B. 90
- C. 96
- D. 108
Ver respuesta y explicación
Respuesta: C. 96
36 records in 45 minutes is 0.8 records a minute. Two hours is 120 minutes, and 120 times 0.8 is 96. You can also see it as a ratio: 45 minutes goes into 120 minutes two and two thirds times, and 36 times two and two thirds is 96. Convert the hours to minutes before you start, because mixing units is the most common slip on rate problems.
18. Thermometer is to temperature as ruler is to what?
- A. Length
- B. Wood
- C. Inch
- D. Measure
Ver respuesta y explicación
Respuesta: A. Length
A thermometer is the tool that measures temperature, and a ruler is the tool that measures length. Say the relationship in a sentence first, then test each choice in the same sentence. Inch is a unit of length rather than the thing being measured, and measure is the action. Analogy items often include a distractor that is related to the right answer but fills a different slot in the sentence.
19. Which word is spelled correctly?
- A. Recieve
- B. Occurence
- C. Separate
- D. Definately
Ver respuesta y explicación
Respuesta: C. Separate
Separate is the right spelling, and the middle is the usual trap: there is an a, as in par, not an e. The others are the classic misspellings of receive, occurrence and definitely. For receive, the rule i before e except after c catches it. For occurrence, remember the double c and the double r. Misspelled words that you have seen wrong a hundred times look right, so say the letters in order instead of judging by eye.
20. A memo says: file the reports by year, newest year first. Within the same year, file them by last name from A to Z. Which order follows the memo?
- A. 2023 Adams, 2023 Brown, 2024 Adams, 2024 Brown
- B. 2024 Brown, 2024 Adams, 2023 Brown, 2023 Adams
- C. 2023 Brown, 2023 Adams, 2024 Brown, 2024 Adams
- D. 2024 Adams, 2024 Brown, 2023 Adams, 2023 Brown
Ver respuesta y explicación
Respuesta: D. 2024 Adams, 2024 Brown, 2023 Adams, 2023 Brown
The first rule puts 2024 ahead of 2023. The second rule only applies inside a year, so Adams comes before Brown in both years. That gives 2024 Adams, 2024 Brown, 2023 Adams, 2023 Brown. Each wrong option breaks exactly one rule, which is how directions items are built. Apply the rules one at a time and cross out the options that fail each one.
21. A policy says: Employees on an eight hour shift take one unpaid 30 minute meal break. The break may not start in the first hour or the last hour of the shift. A supervisor may approve another time for operational reasons only. An employee works 8:00 a.m. to 4:00 p.m. Which meal break is not allowed without a supervisor's approval?
- A. 8:30 a.m. to 9:00 a.m.
- B. 10:00 a.m. to 10:30 a.m.
- C. 12:00 p.m. to 12:30 p.m.
- D. 2:00 p.m. to 2:30 p.m.
Ver respuesta y explicación
Respuesta: A. 8:30 a.m. to 9:00 a.m.
The first hour of this shift runs from 8:00 to 9:00, and a break starting at 8:30 starts inside it, so it needs approval. The last hour is 3:00 to 4:00, and a break starting at 2:00 starts well before it. Items like this ask you to apply a rule to a case, so mark the limits in the passage, then test each option against them. Notice that the question asks which option is not allowed, so three correct looking options are the point.
22. Every employee in the records unit has finished the safety course. Dana has not finished the safety course. Which conclusion must be true?
- A. Dana is in the records unit.
- B. Dana is not in the records unit.
- C. Dana will finish the safety course next week.
- D. Some employees in the records unit have not finished the course.
Ver respuesta y explicación
Respuesta: B. Dana is not in the records unit.
If everyone in the records unit has finished the course, then anyone who has not finished it cannot be in the unit. Dana has not finished, so Dana is not in the records unit. The first option reverses the logic, and the other two add facts the statements never give. For logic items, accept only what the statements force. A conclusion that merely sounds reasonable is wrong.
23. Which of these sentences are punctuated correctly?
Marca todas las que correspondan.
- A. The office opens at 8, and the first clerk arrives at 7:45.
- B. Please send the form, to the records unit.
- C. The records unit moved to the second floor; the permits unit stayed on the first.
- D. Its important to sign the form before you leave.
- E. Applicants must bring a photo ID, proof of address, and a completed form.

Respuesta: A. The office opens at 8, and the first clerk arrives at 7:45., C. The records unit moved to the second floor; the permits unit stayed on the first., E. Applicants must bring a photo ID, proof of address, and a completed form.
A comma plus and joins two complete sentences, a semicolon can join two closely related complete sentences, and commas separate the items in a list. The second sentence has a comma that splits the verb from its object for no reason. The fourth needs an apostrophe, because its important means it is important, so the correct form is it's. The two usual grammar traps are the stray comma and the missing apostrophe.
24. Complete the sentence.
A budget of $2,400 is split so that one fourth goes to supplies and one third goes to salaries. Supplies receive $_____, and salaries receive $_____.
Opciones para el hueco 1: 480, 600, 800, 1,200
Opciones para el hueco 2: 600, 720, 800, 900
Ver respuesta y explicación
Respuesta: 600, 800
One fourth of 2,400 is 600, and one third of 2,400 is 800. Together they take 1,400, which leaves 1,000 for everything else. Fraction of a number problems are division first: split the whole into equal parts, then count the parts you need. If the two shares ever add up to more than the whole, one of the divisions is wrong.
25. Which pair of numbers is exactly the same?
- A. 48172653 and 48172563
- B. 36044817 and 36044871
- C. 92853106 and 92853160
- D. 70915284 and 70915284
Ver respuesta y explicación
Respuesta: D. 70915284 and 70915284
Only the last pair matches digit for digit. The other three pairs swap two neighboring digits, which is the typical error in number checking. To check quickly, split each number into chunks of two or three digits and compare chunk against chunk, or read the pair aloud in the same chunks. Comparing the whole number at a glance is how a swapped pair gets through.
26. A form must be returned within 10 business days of receipt. It was received on Monday, June 3. Counting Tuesday, June 4 as business day 1, and skipping weekends, what is the last day to return it?
- A. Thursday, June 13
- B. Friday, June 14
- C. Monday, June 17
- D. Tuesday, June 18
Ver respuesta y explicación
Respuesta: C. Monday, June 17
Count the business days one by one. June 4 to 7 are days 1 to 4, June 10 to 14 are days 5 to 9, and Monday, June 17 is day 10. Thursday, June 13 is what you get by counting ten calendar days, and Friday, June 14 is what you get by counting the day of receipt as day 1. Read how the problem tells you to start counting, and write down the days instead of working from memory.
27. Your supervisor asks you to process a request on a form, but you notice the form was replaced last month by a newer version. What should you do first?
- A. Process it on the old form because your supervisor asked for it.
- B. Use the new form and say nothing, since it is the current one.
- C. Set the request aside until your supervisor notices.
- D. Tell your supervisor the form was replaced and ask which one to use.
Ver respuesta y explicación
Respuesta: D. Tell your supervisor the form was replaced and ask which one to use.
The best first step tells the person who owns the decision what you noticed and lets them settle it. That keeps the work moving and avoids a wrong form. Using the old form ignores a problem you can see, using the new one without a word changes the instruction on your own, and setting the request aside delays the work. Situational judgment items usually reward the answer that is open, brief and respectful of the chain of command.
28. Which word is closest to the opposite of AMBIGUOUS?
- A. Vague
- B. Clear
- C. Careful
- D. Silent
Ver respuesta y explicación
Respuesta: B. Clear
Something ambiguous can be read in more than one way, so its opposite is something clear, with one meaning. Vague is a synonym, not an opposite, and it is the choice a half remembered word pulls you toward. On opposite items, first find the meaning, then check that the option points the other way. If the options include a synonym, it is there on purpose.
29. Overtime in a department fell from 80 hours one month to 60 hours the next. By what percent did overtime fall?
- A. 20 percent
- B. 25 percent
- C. 33 percent
- D. 40 percent
Ver respuesta y explicación
Respuesta: B. 25 percent
The drop is 20 hours, and percent change is measured against the starting amount. 20 divided by 80 is 0.25, which is 25 percent. Dividing by the new number, 60, gives about 33 percent, which is the usual trap. Always put the old value on the bottom of the fraction when asked how much something fell or rose.
30. Which of these are good practices when you handle confidential records at work?
Marca todas las que correspondan.
- A. Share your password with a coworker who covers your desk.
- B. Lock your screen or log out when you step away.
- C. Take records home to finish them when the office is busy.
- D. Share a person's information only with staff who need it for their work.
- E. Shred printed copies you no longer need.
Ver respuesta y explicación
Respuesta: B. Lock your screen or log out when you step away., D. Share a person's information only with staff who need it for their work., E. Shred printed copies you no longer need.
Confidentiality questions have a simple core: limit who can see the information, and do not let it leave your control. Locking your screen, sharing on a need to know basis and shredding spare copies all do that. A shared password breaks the record of who accessed what, and taking records home puts them somewhere the agency cannot protect. If your agency publishes its own rules, those are the ones the test follows.
No existe un solo civil service exam
Esto es lo primero que hay que dejar claro, porque cambia cómo estudias. No existe un único civil service exam nacional. Las agencias federales, los gobiernos estatales, los condados, las ciudades, las autoridades de transporte, los distritos escolares y los cuerpos de policía y bomberos llevan cada uno su propio proceso de contratación, y cada uno decide qué contiene su prueba escrita. Dos puestos de administrativo en condados vecinos pueden usar pruebas completamente distintas.
Así que ninguna página de internet puede decirte qué va a entrar en la tuya. El número de preguntas, el tiempo límite, la nota de aprobado, cómo se ordena la lista, si los veteranos reciben puntos extra y cuánto tiempo se queda registrada una nota de aprobado los fija la jurisdicción que pone la prueba. Todo lo que fija un estado o un gobierno local de Estados Unidos lo fijan ellos solos, no una norma nacional. Consigue la convocatoria o el manual del candidato de tu número de examen exacto y léelo antes de comprar una sola guía de estudio.
Lo que sí puedes hacer sin ese documento es construir las destrezas de fondo, porque esas se repiten. Una prueba escrita para administrativo de condado y otra para auxiliar de oficina estatal no van a compartir preguntas, pero sí van a compartir las formas de pensar que piden.
Cómo es el proceso de contratación, del anuncio a la oferta
Los detalles cambian según la agencia, pero la mayoría de las contrataciones públicas siguen el mismo camino. Primero, la agencia publica un anuncio con el puesto, el número de examen, los requisitos mínimos, el plazo y la fecha de la prueba. Segundo, te presentas y la agencia comprueba que cumples los requisitos. Tercero, haces la prueba escrita, en un centro de exámenes, en una sesión fija o en línea, según la jurisdicción.
Cuarto, tu nota pasa a una lista ordenada. Algunas jurisdicciones suman puntos por cosas como el servicio militar cuando sus normas lo permiten, y aprobar normalmente solo te mete en la lista, así que tu puesto decide si te llaman. Quinto, la agencia contacta a quienes van arriba en la lista para entrevistas y comprobaciones, y algunos puestos añaden una prueba física, médica o práctica. Al final llega una oferta, o sigues en la lista hasta que caduca. Una lista está vigente un tiempo fijo, así que conviene seguir de cerca una buena nota.
Lee el anuncio para cada uno de estos pasos. Es el único documento que vale para tu examen.
Las destrezas que se trasladan a casi todas
Casi todas las pruebas escritas de civil service beben del mismo conjunto de capacidades generales. La comprensión lectora te pide responder a partir de un texto y solo a partir de ese texto, normalmente un memorando, un aviso o un apartado de un manual de procedimiento. El vocabulario y la gramática te piden elegir la palabra correcta o la frase bien escrita. La aritmética y los problemas se quedan en lo práctico: porcentajes, medias, tasas, repartir una carga de trabajo. Las series de números y letras te piden encontrar la regla que hay detrás de una secuencia. Las preguntas espaciales y de patrones te piden imaginar algo doblado, girado o montado.
El resto del conjunto es administrativo. Las preguntas de memoria y observación te dan detalles y luego te piden recordarlos con exactitud. Las de codificación te entregan una clave y una regla y te piden aplicarla sin resbalar. Las de archivo evalúan el orden alfabético y numérico. El cotejo administrativo te da dos listados y pregunta si coinciden, lo que suena fácil hasta que te encuentras un dígito cambiado de sitio a toda velocidad. Las de juicio situacional describen un problema con un compañero o con una persona del público y preguntan qué harías primero.
Esta muestra pone al menos una pregunta de cada uno de esos estilos. Hazla de una sentada y sin apuntes, después lee la explicación de cada pregunta, también de las que acertaste. Trata una respuesta fallada como una destreza que entrenar y no como un dato que memorizar. Fallar una pregunta de cotejo y una de observación apunta al mismo hábito, que es leer en bloques enteros en vez de campo por campo.
Cómo afrontar cada tipo de pregunta
Comprensión lectora: lee primero la pregunta, después el texto, y responde solo con lo que dice el texto. Cuidado con las palabras fuertes como siempre, nunca y todos, que casi nunca están respaldadas.
Vocabulario, ortografía y gramática: encuentra el significado o la regla antes de mirar las opciones, y espera entre ellas un casi opuesto o una falta de ortografía típica.
Aritmética y problemas: escribe el planteamiento antes de calcular. Convierte primero todas las unidades a la misma, en un cambio porcentual pon el valor antiguo en el denominador y comprueba que el resultado tiene un tamaño razonable.
Series y razonamiento: mira las diferencias entre números, convierte las letras en su posición en el alfabeto y prueba tu regla con el último término que te dieron.
Cotejo, codificación y archivo: suelen ser pruebas de velocidad, así que cuentan a la vez la precisión y el ritmo. Compara por bloques en vez de cadenas enteras, aplica la clave exactamente como está escrita y sigue las reglas de archivo en el orden en que te las dan.
Criterio ante situaciones laborales: elige la respuesta que resuelve el problema, mantiene la calma y respeta la cadena de mando. Descarta las que culpan, evitan o puentean a las personas.

Obtienes un test escrito a partir de esas páginas exactas, y cada explicación cita de dónde sale la respuesta, así que puedes ir directo a la fuente cuando algo no cuadre.
Para el resto está Bo, el tutor. Pregúntale por qué una respuesta es correcta y te contesta desde tus propias páginas, con una pista primero si la quieres. Si le pides un test de práctica, te da el formulario de Nuevo material ya rellenado. El test no lo construye dentro del chat.
No hace falta subir nada para empezar. Nombra un tema, por ejemplo series de números o cotejo de datos. Basta una cuenta gratis, sin tarjeta y sin límite de tiempo. El plan gratis cubre unos cuatro materiales nuevos por semana, y Pro y Ultra cubren más.
