I have two lessons, politics and history. In politics we won't be doing anything that I can't find out about and learn from the text-book, and in history I'll miss out on some information regarding various aspects of Nikita Khrushchev's leadership of the Soviet Union, which'll be more difficult to catch up on. I feel I'll be more productive at home, though, instead of spending three hours doing nothing at college for my free periods.
So, fuck it, your call.
