Three weeks sounds like a lot, but split across five or six subjects, each one only gets a few sessions. A clear plan from day one saves you from cramming the night before.
Before you start: map it out
Spend your first session planning, not studying. It feels like lost time, but it's the hour that makes the other three weeks work.
- List every exam: subject, date, time and format (multiple choice, essay, problems).
- Rate each subject: from 1 to 5, how confident do you feel? Low scores and early dates get more time.
- Gather your materials: notes, slides, past exams. Find out now what's missing, not in week 3.
Week 1: review everything
- Two subjects a day, skimming the syllabus and your notes for each.
- Mark the parts that feel fuzzy. You don't need to understand them yet.
The goal this week is a map of what you know and what you don't. Move quickly. If you get stuck on one topic for too long, mark it and keep going. By the end of the week, every subject should have a short list of weak spots.
Week 2: fill the gaps
- Go back to the marked parts, doing hard subjects in the morning while your mind is fresh.
- Keep one weekend day free to make up for missed sessions.
This is the heaviest week. Work through your weak-spot lists with active methods: practice problems, flashcards, explaining a topic out loud. Rereading feels comfortable, but it won't fix the gaps you found in week 1.
Ask for help early. If a topic still doesn't make sense after one honest attempt, ask a classmate or your teacher this week, while there's still time to practise it.
Week 3: practice exams
- Work through past exams, timed like the real thing.
- Get a full night's sleep before exam day. An extra hour of review can't make up for a sleepless night.
Mark each practice exam honestly, then spend more time on your mistakes than on the exam itself. Each wrong answer tells you exactly what to review next. If your exams are spread out, keep revising the later subjects in between instead of resting until the last one.
What a study day can look like
- Morning: two 50-minute blocks on your hardest subject.
- Afternoon: two or three blocks on a second subject, or practice problems.
- Evening: a short flashcard review of both subjects, then stop at a fixed time.
That's around five to six hours of real study, which is plenty. More than that, and the quality usually drops faster than the hours go up.
If you fall behind
You will miss a session at some point. That's what the free weekend day is for. If you fall behind by more than a day, don't try to cram everything back in. Cut the lowest-value topics instead, the ones that are unlikely to come up or worth few marks, and protect the rest of the plan.
The last two days
Stop learning new material. Go over your summary notes, the flashcards you keep getting wrong, and the mistakes from your practice exams. Pack your bag the evening before and go to bed on time.
A plan you can stick to beats a perfect plan you abandon by week two.
