hi, I'm currently in yr13 and I wanted to ask previous A-level students, what the right time is to start revising for year 13 mocks. I have them in january so is a month before the right time to start? or should I start even earlier in November? also, how do ik what content is gonna come up in my mocks? is it everything we've learned in yr12 and yr13 so far? or just yr12 content?
