How do you study engineering?

Study engineering by working problems, not just reading. Solve many problem sets, and make sure you understand where each formula comes from, not only what it spits out. Redo the hard problems from scratch a few days later until you can do them clean. Keep one page of key equations with a note on when to use each.

Engineering is a doing subject. You can read a chapter twice and still freeze on the exam, because the exam asks you to solve, not to recite. So spend most of your time with a pen, working problems. Start with the worked examples, then close the book and redo them from memory. Then move to new problems you have not seen.

Don't stop at the formula. Understand the derivation. When you know why an equation looks the way it does, you can rebuild it under pressure and you can tell when it does not apply. If a derivation feels like magic, explain it out loud in plain words. The spot where you get stuck is the part you don't actually get yet.

The hardest problems are the ones worth repeating. If a problem beat you, mark it and come back in a few days. Redo it with a blank page. Once you can solve it without hints, it is yours. Build a one-page sheet of the key equations and a short line next to each saying when you reach for it.

Where to spend your time
ActivityGood or badWhy
Rereading the textbookWeakFeels like studying, but you never practice solving
Working new problemsStrongTrains the exact skill the exam tests
Memorizing formulas onlyWeakBreaks on any problem that looks a bit different
Understanding the derivationStrongLets you rebuild the formula and spot when it fits
Redoing hard problemsStrongTurns your weak spots into solid ones
Step by step
  1. 1Work problems every day, more than the homework asks. Quantity matters here.
  2. 2For each formula, follow the derivation once so you know where it comes from.
  3. 3Redo worked examples from memory with the book closed, then check.
  4. 4Mark the problems that beat you and redo them from scratch a few days later.
  5. 5Build a one-page sheet: key equations plus a note on when to use each.
  6. 6Time yourself on old exams under real conditions before the test.
How StudyPDF helps

Do it on your own course

Upload your lecture slides, problem sets and notes, and Bo builds a practice exam and quizzes from them, then tracks which problems you keep getting wrong so it can drill those. It can also pull your key formulas into a one-page cheat sheet, with every answer linked to the page it came from.

More questions

Should I memorize formulas or understand the derivation?

Understand the derivation first. Once you know why a formula looks the way it does, you can rebuild it on the exam if you blank, and you can tell when it does not apply. A few core formulas are worth memorizing for speed, but understanding always comes first. Memorizing without understanding breaks the moment a problem looks a little different.

How many practice problems are enough?

More than the homework gives you. Homework alone is rarely enough to make a topic automatic. Do the assigned set, then find extra problems from old exams, the textbook, or other sources. The goal is to solve a hard problem cleanly without looking at notes. When you can do that for each problem type, you have done enough.
