How to manage time for A levels?

-I,m doing 3 alevel subjects after summer and was wondering how to manage the free time i get and what to do with it. I,m taking advance english and lit, chinese cultural studies, history. i,m probably going to have to read alot >< but was wondering if you people that already did the course can give me advice on what you,d wish you had done and what i should do to do well. Thanks alot really appreciate it =DDon't procrastinate. Get and use a calendar and schedule everything there. Make sure you commit to what you put in there and stick to it.
