1. 1. Which version of the sentence is punctuated correctly?

   • A. The storm knocked out power for two days, we cooked everything on a camp stove.
   • B. The storm knocked out power for two days; we cooked everything on a camp stove.
   • C. The storm knocked out power for two days we cooked everything on a camp stove.
   • D. The storm knocked out power for two days, and, we cooked everything on a camp stove.
   Vis svar og forklaring

   Svar: B. The storm knocked out power for two days; we cooked everything on a camp stove.

   Both halves of this sentence can stand alone, so joining them with only a comma creates a comma splice. Two independent clauses need a semicolon, a period, or a comma followed by a joining word such as and or so.

2. 2. Complete the sentence.

   The box of old photographs that my grandparents kept in the attic _____ finally been opened.

   Muligheder for felt 1: have, has, having, were

   Vis svar og forklaring

   Svar: has

   The subject is box, which is singular, so the verb is has. The ACT often buries the subject by putting a prepositional phrase and a relative clause between it and the verb, so find the subject before you decide on the verb form.

3. 3. A paragraph reads: In its first year, the school's bike repair club fixed 140 bicycles for students who would otherwise have paid a shop. The writer wants to end the paragraph with a sentence that supports its point about saving students money. Which choice does that best?

   • A. A basic tune-up at a local shop starts at about forty dollars, so the club kept thousands of dollars in students' pockets.
   • B. The club meets on Tuesdays in the shop room behind the gym.
   • C. Bicycles have been a common way to get around the city for decades.
   • D. Two members of the club later joined the track team.
   Vis svar og forklaring

   Svar: A. A basic tune-up at a local shop starts at about forty dollars, so the club kept thousands of dollars in students' pockets.

   Rhetorical skills questions are decided by the purpose stated in the question, not by which sentence sounds nicest. Only the first choice puts a number on the money saved, while the others are true sounding details that never touch cost.

4. 4. Which of these sentences use an apostrophe correctly?

   Vælg alle, der passer.

   • A. The team celebrated its first win in three years.
   • B. It's been a long season for the coaching staff.
   • C. Both players' jerseys were retired on the same night.
   • D. The bus left without it's driver.
   • E. The Wilsons' invited us to dinner.
   Vis svar og forklaring

   Svar: A. The team celebrated its first win in three years., B. It's been a long season for the coaching staff., C. Both players' jerseys were retired on the same night.

   Its is the possessive form and takes no apostrophe, while it's is only ever a contraction of it is or it has. A plural that already ends in s takes the apostrophe after the s, as in players' jerseys, and a plain plural family name like the Wilsons takes no apostrophe at all.

5. 5. A jacket is marked down 30 percent, and the sale price is $84. What was the original price?

   • A. $109.20
   • B. $114.00
   • C. $120.00
   • D. $126.00
   Vis svar og forklaring

   Svar: C. $120.00

   A 30 percent discount leaves 70 percent of the original price, so solve 0.7x = 84 and get x = 120. Adding 30 percent back onto the sale price gives $109.20, which is the trap answer, because the percent was taken from the larger number.

6. 6. What is the slope of the line that passes through the points (-2, 5) and (4, -7)?

   • A. -2
   • B. -1/2
   • C. 1/2
   • D. 2
   Vis svar og forklaring

   Svar: A. -2

   Slope is the change in y over the change in x, so (-7 - 5) divided by (4 - (-2)) gives -12 over 6, which is -2. Watch the signs in the denominator, since subtracting a negative x value is the most common place this goes wrong.

7. 7. Complete the sentence.

   In a right triangle, the leg opposite angle A measures 5 and the hypotenuse measures 13, so sin A equals _____.

   Muligheder for felt 1: 5/12, 5/13, 12/13, 13/5

   Vis svar og forklaring

   Svar: 5/13

   Sine is the opposite side over the hypotenuse, which is 5 over 13. The third side is 12 by the Pythagorean theorem, so 12/13 is cos A and 5/12 is tan A, and those are the choices that catch people who mix up the three ratios.

8. 8. Which of the following values are solutions to the equation x squared minus x minus 6 equals 0?

   Vælg alle, der passer.

   • A. -3
   • B. -2
   • C. 0
   • D. 2
   • E. 3
   Vis svar og forklaring

   Svar: B. -2, E. 3

   The expression factors into (x - 3)(x + 2), so the solutions are 3 and -2. Checking beats trusting the factoring: 9 minus 3 minus 6 is 0, and 4 plus 2 minus 6 is 0, while -3 gives 9 plus 3 minus 6, which is 6.

9. 9. Read the passage. When the Millbrook library ran out of shelf space, the head librarian did something odd with the empty basement room: she filled it with hammers, drills and a tile saw. Patrons could borrow a tool for a week the same way they borrowed a novel. Within two years the tool collection was checked out more often than the fiction shelves. Some staff were skeptical, and the repair bills were real, but the librarian argued that a library lends access, and access does not have to come in the shape of a book. The main idea of the passage is that:

   • A. the Millbrook library had run out of shelf space.
   • B. libraries should spend less money on fiction.
   • C. one library widened what lending can mean, drawing doubts from staff but clear demand from patrons.
   • D. most people find tools more useful than novels.
   Vis svar og forklaring

   Svar: C. one library widened what lending can mean, drawing doubts from staff but clear demand from patrons.

   A main idea has to cover the whole passage, not one sentence of it. The shelf space problem is only the setup, and the last two choices are broad claims about libraries and readers in general that this passage never makes.

10. 10. Passage A: Rewilding a river means taking out what we built and stepping back. When the Corbin Dam came down, the channel rearranged itself in a single spring flood, and the fish returned without anyone stocking them. Nature keeps a blueprint we cannot draw. Passage B: Taking out a dam is not stepping back, it is one more decision. Someone picks which structure goes, which floodplain gets bought, and who pays for it. Rivers do recover, but calling that recovery natural hides the engineering and the money behind it. Both authors would most likely agree that:

    • A. a river can recover ecologically after a dam is removed.
    • B. people should stop managing rivers.
    • C. dam removal costs too much to be worth doing.
    • D. fish populations return only when they are restocked.
    Vis svar og forklaring

    Svar: A. a river can recover ecologically after a dam is removed.

    Paired passage questions ask you to find the narrow patch of common ground, not the argument. Passage A says the fish came back on their own and passage B says rivers do recover, so the two disagree about what to call the recovery rather than about whether it happens.

11. 11. Complete the sentence.

    Marisol read the committee's letter twice, set it down, and spent the rest of the afternoon rearranging books that were already in order. The narrator most likely wants readers to understand that Marisol is _____ the news in the letter.

    Muligheder for felt 1: indifferent to, unsettled by, delighted by, confused by the wording of

    Vis svar og forklaring

    Svar: unsettled by

    Inference questions ask what the details imply, and here the rereading plus the pointless busywork signal agitation the narrator never names outright. Indifference is ruled out by the second reading, and nothing in the scene suggests pleasure or trouble understanding the words.

12. 12. A student dropped one tablet of compound Z into 200 mL of water and timed how long it took to dissolve completely, repeating the trial at four water temperatures. Trial 1: 10 degrees C, 96 seconds. Trial 2: 20 degrees C, 62 seconds. Trial 3: 30 degrees C, 41 seconds. Trial 4: 40 degrees C, 28 seconds. Based on these results, a tablet dropped into water at 25 degrees C would most likely take about how long to dissolve?

    • A. 24 seconds
    • B. 35 seconds
    • C. 51 seconds
    • D. 70 seconds
    Vis svar og forklaring

    Svar: C. 51 seconds

    25 degrees falls between trial 2 and trial 3, so the dissolving time falls between 62 and 41 seconds, and 51 seconds is the only choice in that range. Notice that you never needed to know what compound Z is, which is the point: the science section is a data reading test, and it often uses substances and setups you have never met.

13. 13. A student wants to test whether adding salt changes how long water takes to freeze. Which of the following should be kept the same in every trial?

    Vælg alle, der passer.

    • A. The starting temperature of the water
    • B. The volume of water in each container
    • C. The freezer setting
    • D. The amount of salt added
    • E. The time each sample takes to freeze
    Vis svar og forklaring

    Svar: A. The starting temperature of the water, B. The volume of water in each container, C. The freezer setting

    Everything except the one variable you are testing has to be held constant, or you cannot tell what caused a difference. The amount of salt is the variable being changed on purpose, and the freezing time is the result being measured, so neither one can be controlled.

14. 14. Two scientists explain why dissolved oxygen in a lake has fallen. Scientist 1 says fertilizer running off nearby fields feeds algae, and the algae die and decay, which uses up oxygen. Scientist 2 says the lake water has warmed, and warmer water holds less dissolved oxygen. Which finding, if confirmed, would most weaken Scientist 2's explanation?

    • A. Lake water temperature rose by 3 degrees C over the same period.
    • B. Oxygen fell just as sharply in a nearby lake whose temperature did not change.
    • C. Algae counts in the lake rose over the same period.
    • D. Cold water is able to hold more dissolved oxygen than warm water.
    Vis svar og forklaring

    Svar: B. Oxygen fell just as sharply in a nearby lake whose temperature did not change.

    A case where the effect appears without the proposed cause is the strongest evidence against that cause, so an unwarmed lake losing oxygen just as fast undermines the temperature explanation. Rising algae counts support Scientist 1 without weakening Scientist 2, because both processes could be draining oxygen at once.

15. 15. Figure 1 plots the size of two bacterial cultures over 8 hours. Culture A rises in a straight line from 200 cells per mL at hour 0 to 1,000 cells per mL at hour 8. Culture B holds steady at 800 cells per mL through hour 4, then falls in a straight line to 400 cells per mL at hour 8. According to Figure 1, at about what time are the two cultures the same size?

    • A. Hour 2
    • B. Hour 4
    • C. Hour 5
    • D. Hour 7
    Vis svar og forklaring

    Svar: C. Hour 5

    Culture A gains 100 cells per mL each hour, so it sits at 700 at hour 5, and culture B loses 100 per hour after hour 4, so it is also at 700 at hour 5. When a question asks when two things are equal, look for where the lines cross rather than reading each line on its own.

Hvad ACT faktisk indeholder

ACT er en multiple choice-prøve bygget af fire fagområder: engelsk, matematik, læsning og naturfag. Hver del, du tager, scores på en skala fra 1 til 36, og din composite er gennemsnittet af de delscorer, rundet af. Der er et valgfrit essay, som scores for sig på sin egen skala, og det ændrer ikke din composite. Der trækkes ikke fra for et forkert svar, så der er aldrig grund til at lade et spørgsmål stå tomt.

Formatet har ændret sig, og det betyder mere end normalt lige nu. Fra 2025 begyndte ACT at udrulle en kortere udgave af prøven: færre spørgsmål, mere tid per spørgsmål, og naturfag som en valgfri del frem for en obligatorisk. I den udgave kommer din composite fra engelsk, matematik og læsning, og en naturfagsscore opgives separat, hvis du vælger at tage den. Hvilken udgave du kommer til at sidde med, kan afhænge af din prøvedato og af, om du tager prøven online eller på papir, så behandl ethvert fast antal spørgsmål, du læser nogen steder, også i en ældre forberedelsesbog og også på denne side, som noget der skal bekræftes. Tjek det officielle ACT-format for din egen prøvedato, før du bygger en tempoplan op om et tal.

Hvad hver del spørger om, har ligget mere fast end antallene. Engelsk tester sprogbrug og formalia, altså tegnsætning, grammatik og sætningsopbygning, plus retoriske færdigheder, altså opbygning, stil og om en sætning overhovedet hører til i afsnittet. Matematik går fra pre-algebra og elementær algebra over analytisk geometri og plangeometri til lidt trigonometri. Læsning er tekstbaseret: hovedbudskab, understøttende detaljer, slutninger, ordforråd i kontekst og spørgsmål, der sammenligner to tekster om samme emne. Naturfag giver dig tabeller, grafer og konkurrerende forklaringer og beder dig læse dem.

Sådan bruger du smagsprøven

De 15 spørgsmål følger ACT's indholdsfordeling i miniature. Engelsk får den største andel, fordi det bærer flest spørgsmål på den rigtige prøve, matematik kommer derefter, og læsning og naturfag fylder resten. Den rigtige ACT er multiple choice fra start til slut. Denne smagsprøve bruger også vælg alle der passer og udfyld det tomme felt, fordi de formater er sværere at gætte sig igennem, og det gør dem til et bedre tjek på, om du faktisk kan reglen.

Tag den i ét stræk uden noter og uden lommeregner. ACT belønner tempo mere end de fleste prøver gør, og i det lange format gav den dig et godt stykke under et minut per spørgsmål i flere dele. Det korte format lettede det uden at fjerne det, så det er lige så meget værd at øve sig i et tempo, hvor du binder dig til et svar og går videre, som det er at repetere fagligt stof.

Læs derefter forklaringen til hvert spørgsmål, også dem du svarede rigtigt på. Et forkert svar peger som regel på en færdighed frem for på et faktum. Hvis du missede spørgsmålet om komma mellem helsætninger og spørgsmålet om apostrof, så repeter tegnsætning som ét emne i stedet for at lære to sætninger udenad. Og hold øje med, hvad du gjorde ved naturfagsspørgsmålene: greb du efter noget, du halvt husker fra biologitimerne, i stedet for at læse tallene foran dig, vil den vane koste dig point på den rigtige prøve.

Sådan bygger StudyPDF fulde øveprøver ud fra dit eget materiale

Femten spørgsmål kan vise dig, hvilke områder der vakler. De kan ikke gøre dig klar alene, og et generisk spørgsmålssæt aner ikke, hvilke kapitler dit hold faktisk har været igennem, eller hvilke fejl du bliver ved med at gentage.

StudyPDF arbejder ud fra dit materiale i stedet. Upload din ACT-forberedelsesbog, dine noter fra timerne eller en øveprøve, din lærer har rettet, og Bo, studieagenten, bygger fulde øveprøver ud fra præcis de sider. Hvert spørgsmål bygger på det, du har uploadet, og hver forklaring henviser tilbage til hvor svaret kom fra, så du kan tjekke kilden når noget ser forkert ud. Du kan lave en ny prøve så tit du vil, holde den på ét område som trigonometri eller kommaregler, og se hvilke emner du bliver ved med at ramme forkert.

Du behøver ikke et dokument for at komme i gang. Du kan også bare nævne et emne, for eksempel ACT-dataaflæsning i naturfag eller kongruens mellem subjekt og verbum, så skriver Bo et øvesæt ud fra det i stedet. Gratis at komme i gang.
