How to study for exams: a plan for the weeks before
To study for an exam, find out exactly what it covers and how it is marked, then spend most of your time answering questions rather than rereading. Start about three weeks out: make sure every unit has notes, test yourself on each one, and repeat the units you get wrong. In the final days, take full practice tests under real conditions and sleep properly.
Step one: know the exam
Read the syllabus again. Write down the date, the weight, the units it covers, the format (multiple choice, short answer, calculations, essays) and any rules, like formula sheets. Then look for past exams or practice questions from the course. Everything else in this plan depends on these facts.
Three weeks out
- Make sure every unit on the exam has notes you can study from. Fill gaps now, not in the final week.
- Make a one-page study guide for each unit.
- Take a short practice test on each unit and sort them into strong and weak.
Two weeks out
- Spend most of your time on the weak units, using active recall: flashcards, the blank page, practice questions.
- Revisit the strong units briefly every few days so they stay strong. Spacing beats cramming.
- Do the past exams if you have them, untimed, and study every mistake.
The final week
- Take full practice tests under real conditions: timed, closed book, then mark them honestly.
- For each mistake, write down why you made it. Most fall into a few patterns, like misreading the question or a formula you mix up.
- Review your study guides daily. They should be the last thing you read, not the first.
The day before
Do a short review of your study guides and the mistakes list, then stop. Pack what you need, and sleep. Memory consolidates during sleep, and an all-nighter costs more than it gains.
Midterms and finals
A midterm covers a few units, so start about two weeks out and compress the plan. A final often covers everything, so check whether it weights later units more and give those more time. In both cases, practice testing beats rereading.
Questions students ask
How long before an exam should I start studying?
About three weeks for a final and two for a midterm, with short sessions most days. Starting earlier lets you space your review, which helps memory.
Is it better to study a little every day or cram?
A little every day. Spreading study out is one of the most reliable findings in learning research, and cramming fades fast.
What should I do the night before an exam?
A short review of your study guides and your list of mistakes, then sleep. Avoid learning new material.
How do I study when I have several exams?
Lay out every exam date on one calendar, start with the earliest, and keep a short daily review going for the later ones.
