How consistent are you?
Most people revise a few days or a week before.
Or hell they:
Revise just after they had a lesson
Then Revise a week later.
And they review their knowledge.
But some are just blessed eith great memory and can just do with 2 days before exam revision with hard hard cramming.
The thing about using topicals is to make flashcards about every question you got wrong to consolidate your learning.
Don't cram if you want better grades. And if you don't have time. Make some.
