Q: My mom keeps telling me to revise lessons before examination. When I have already learned well, what is the use of revision?
A: Revision is not about memorising facts but trying to understand your subject well enough to demonstrate familiarity with its big themes regardless of a specific question. If you only mug up three to five answers, you will be stumped if not enough of them come in your exams. You also probably know a lot more than you imagine. It would be a good idea to do a couple of sample papers by yourself under real conditions and then direct your revision to your weaker topics.
