Aim for short, focused sessions (around 45 minutes with a break), use active methods like practice questions and self-testing rather than re-reading, rotate subjects through the week, and add timed past papers in the final months.
How much study is enough?
It varies by student and time of year. A common pattern during term is one to two focused hours on school days, more at weekends and much more in the months before exams. Consistency beats marathon sessions.
Use active methods
| Less effective | More effective |
|---|---|
| Re-reading notes | Answering questions from memory |
| Highlighting | Making and using flashcards |
| Copying notes neatly | Explaining a topic aloud |
| Reading the mark scheme | Attempting the question first, then marking it |
The most effective methods all involve retrieving information, not just looking at it.
A sample weekday routine
| Time | Activity |
|---|---|
| After school | Break, food, rest |
| Session 1 (45 min) | Homework or the hardest subject |
| Break (10 min) | Move, water, no phone scrolling |
| Session 2 (45 min) | Review: flashcards or practice questions |
| Evening | Light review, then sleep on time |
Weekly rhythm
- Rotate subjects so each one gets attention every week
- One past-paper question set per subject each week in the exam year
- Review mistakes: keep an error log by topic
The final three months
Shift towards full timed past papers under exam conditions, then mark them against the mark scheme and fix the topics where marks are lost. Read how to use past papers effectively.
Sleep, breaks and phones
Sleep consolidates memory; all-nighters undo it. Phones in another room during study sessions make a bigger difference than most students expect.

Frequently asked questions
How many hours should an O Level student study daily?
During term, around one to two focused hours on school days is common, increasing in the months before exams. Consistency matters more than long sessions.
What is the best way to revise for IGCSE?
Active methods: practice questions, flashcards, explaining topics aloud and timed past papers marked against the mark scheme.
When should I start past papers?
Start with topic questions early in the exam year, and move to full timed papers in the final few months.
Is it better to study late at night?
Regular sleep helps memory. A consistent routine earlier in the evening usually works better than late-night cramming.
