How to Revise Effectively
- Read the notes actively — test yourself after each section.
- Use the Feynman technique — explain each concept aloud in simple words.
- Highlight anything you cannot recall instantly — revise it again the next day.
- Combine with practice problems — revision without application is incomplete.
Last-Minute Revision Strategy
- Day before the exam — only review your notes and formula sheet.
- Morning of the exam — spend 30 minutes on the hardest concepts.
- Do not start new topics — only revise what you have already studied.
- Stay calm — you know more than you think.

Start freeFrequently Asked Questions
How many days before the exam should I start revision?
Start at least 15–20 days before. The last 5 days should be pure revision with no new topics.
Are revision notes enough to score well?
Revision notes are for consolidation, not first-time learning. Study the textbook first, then use notes for quick recall.
What is the best time to revise?
Many students find early morning and a short session before sleep work well. Sleep helps your brain consolidate what you revised, so don't give it up to cram.
