How to Study for Exams: A Plan That Actually Works
· 3 min read
To study for an exam, turn your notes into questions, answer them from memory on spaced days, and sit one timed paper before the real one. That is most of it. The reason it rarely happens is that rereading and highlighting feel productive, cost no effort, and leave you surprised in the exam room.
What the research says works
In 2013 a team led by John Dunlosky reviewed hundreds of studies on ten common study techniques. Two came out clearly on top: practice testing and distributed practice, which means spreading study over time. Highlighting, rereading, and summarising were rated low utility.
That is uncomfortable, because the low-utility methods are the ones most students use. They feel fluent. Fluency is not memory. The effective methods feel slower and more effortful, and that effort is the point.
Step one: turn notes into questions
You cannot test yourself on a page. You need questions. For each lecture, write or generate a handful of questions whose answers are in your notes: definitions, steps, causes, comparisons, and one “explain why”.
Use the wording your lecturer used. The exam is written by the same person.
Try this: If a heading in your notes cannot be turned into a question, it is probably not going to be examined. If it can, it should be a card.
Step two: answer before you look
Cover the answer, say or write yours, then check. Mark yourself honestly. Anything you hesitated on counts as a miss. Misses come back sooner. Answers you knew can wait a few days.
Mix topics once you have covered a few. Questions from different lectures, shuffled, are harder and closer to the exam.
A week-by-week exam study plan
Adjust the weeks to your date. The order matters more than the exact numbers.
- Six weeks out: cover every topic once, with a short quiz after each.
- Five to three weeks out: daily due reviews of 15 to 30 minutes, plus a mixed quiz each week.
- Three to two weeks out: sit a full timed mock. List what fell apart.
- The next week: spend most of your time on that list, not on what you already know.
- Last week: a second mock early in the week, then short mixed quizzes on weak topics.
- Night before: a light review, everything packed, and a full night’s sleep.
If the exam is in a few days
Do not try to read everything. Pick the topics most likely to be examined and the ones you are weakest in. Quiz yourself on those, read only the pages for your misses, and quiz again the next day. Two days of testing beat two days of reading every slide once.
Sleep is part of the plan
Memory is consolidated during sleep. An all-nighter trades the hours you most need for remembering for a few extra hours of tired reading. If you have to choose between one more chapter and sleep, sleep usually scores higher.
Common questions
How many hours a day should I study for exams?
Two to four focused hours a day is plenty for most students in the weeks before exams, with breaks. Count questions answered and topics fixed, not hours sat at a desk.
Is it better to study a little every day or a lot at once?
A little every day. Spacing is one of the most reliable findings in learning research: the same total time spread over more days leads to longer-lasting memory.
How do I study for an exam when I have no past papers?
Make questions from your own notes and sit them under timed conditions. Calm Study writes quizzes and a mock in your institution’s format from the notes you upload, so you are not stuck without practice material.
Should I rewrite my notes to revise?
Only if rewriting means closing the notes and writing what you remember. Copying notes neatly feels productive but is close to rereading.
Calm Study
Calm Study does the setup for this plan. Upload your notes and it writes the questions, brings back the ones you miss on a spaced schedule, writes a mock in your institution’s shape, and names what to study each day from your exam date.
