I'm in my final GCSE year, and I'm going on to do 5 A-levels next september; Maths, Further Maths, Chemistry, Physics, and Biology. Is it worth me doing work for these this summer and getting some of the stuff learned before I actually start the AS's, or will it just be a waste of time?
I was planning on doing 4 hours a week of chemistry, and 2 hours a week of maths as I know my workload will be high, so is it a good idea?
