How to revise effectively
Start with the big picture
The summary video and mind map give you the chapter’s structure before you dive into the details.
Practise under exam conditions
A timed mock exam reveals what you are really missing more effectively than rereading your notes.
Space out your revision
Revisiting a concept after 1, 3, 7 and then 14 days helps it stick: that is what spaced repetition does.
Focus on your weak spots
The Progress page shows you which topics to prioritise and estimates your grade.
