Have you asked yourself this question?
I was a little stumped the first time I was asked it, since it’s a personal decision on what, where and when to start revising. How can someone else answer that for you?
But then I realised that it’s a fair question, especially when you’re trying to work out where best to spend your time revising. Nevertheless, my answer then, as now, was “…it depends”.
When you’re building your study plan, the time you set aside to revise or learn different topics all depends on how much time you have in total to study.
