How to Study for Exams

Hours spent are not what decides an exam. What decides it is whether you can pull the answer out of your own head, under time, on the day. Everything below trains exactly that.

The short answer

  1. List every topic the exam can ask, from the syllabus or past papers, not from your notes.
  2. Count back from the exam date and give each topic its days, with the last week kept for full practice.
  3. Test yourself instead of re-reading: close the book and write or say what you remember, then check.
  4. Revisit each topic after a day, a week and before the exam, so it is still there when you need it.
  5. Finish with past papers under time, and spend most of your last days on what you got wrong.

Start from what is examined

Your notes cover what was taught. The exam covers what is in the syllabus. Start from the syllabus or the last three past papers and write one line for each topic. That list is your study plan's backbone, and it shows the topics your notes skipped.

Mark each topic: green if you could explain it now, amber if you half know it, red if it is new. Red and amber get most of the time.

Count back from the exam date

  1. Keep the last week for practice. Full past papers under time, and fixing what they show.
  2. Share the rest between topics. Red topics get two or three sessions, amber two, green one.
  3. Plan short sessions. Twenty-five to forty minutes on one topic, then a short break. Two or three a day beats one long night.
  4. Leave one free day a week. Plans slip. A spare day keeps one bad evening from breaking the whole plan.

Test yourself instead of re-reading

Re-reading feels productive because the page looks familiar. Familiar is not the same as remembered. The method that works is active recall: you try to bring the answer back without looking, then you check.

  • After reading a section, close it and write the key points from memory. Then compare.
  • Turn each topic into questions and answer them out loud or on paper.
  • Use flashcards for facts, terms and formulas, one idea per card, with the answer on the back.

Revise at the right moments

Memory fades fast at first and then more slowly. Coming back to a topic just as it starts to fade fixes it far longer than studying it twice in one day.

WhenWhat to do
The next dayFive minutes of recall on yesterday's topic.
A week laterAnswer its questions again; redo the ones you missed.
The week before the examA past paper that includes it, under time.

The last week and the day itself

  • One past paper a day, under time, then mark it and fix what it shows. That is the most valuable hour of the week.
  • Keep a "mistakes" page and read it every evening.
  • Sleep. A night's sleep after studying is when memory settles. Staying up late the night before costs more than it gains.
  • On the day, read every question once before you start, and answer the ones you are sure of first.

Your exam study plan

  1. List every examined topic from the syllabus or past papers.
  2. Mark each topic green, amber or red.
  3. Count back from the exam date; keep the last week for past papers.
  4. Study in 25 to 40 minute sessions, one topic each.
  5. Close the book and recall; then check.
  6. Revisit each topic after a day, a week, and the week before.
  7. Last week: one timed past paper a day, and a mistakes page.
  8. Sleep well the night before.

Frequently asked questions

How many hours a day should I study for exams?

Two or three focused sessions of 25 to 40 minutes beat one long night. What matters is testing yourself in each session, not the hours.

Is re-reading my notes a good way to study?

It is the weakest way. Closing the notes and recalling what they say, then checking, works far better.

When should I start studying for an exam?

As early as you can give each examined topic two or three sessions plus a final week of past papers. Count back from the date to see how many days that is.
