I did AS Levels in Biology, Chemistry, Mathematics and Psychology and a GCSE Italian last year, plus 2 tutorials, 1 RE and 1 Key Skills lesson. Had no free time at all. The earliest I finished was on Tuesday at 3:30pm. Of course, the work is harder but if you're organised and don't dump your work anywhere, then it's manageable. It's basically like secondary school, with 3:30pm finishes everyday.
It has made me appreciate my free time more this year. I have dropped Biology and now have a free 45-minute period on Tuesdays, a late start at 11am on Wednesdays and an early finish at 12:30pm on Fridays. The free periods also seem to make the week go quicker. I can't believe that I only have about 2 months left of college left.
