What are "revisions"?

[Johnny L.A.]

British students are always talking about "revisions". "I've been doing my revisions for hours!" or "I'd love to come, but I have to do my revisions".

What are "revisions"?

I suspect it's revision, singular. They're swotting. Studying. Looking over recently-taught material in order to better comprehend it.

"revision", "to revise" is going back over all the work you've done usually to get ready for an exam.

"to revise" is going back over all the work you've done usually to get ready for an exam.
Aha. From the context I knew it meant "studying" or "cramming"; but I kept thinking, "What is there to revise? Don't they write down the correct information to begin with?"

So what's a "revision timetable"? Just an appointment with yourself to set aside a given block of time to study a given subject?

revision timetable is something that you are encourage to do before the big (GCSE/A-Level/degree) exams. Just basically organising your revision so you cover all subjects/areas and building in breaks and free time.
