I don't know about your classes, but I did science at a fairly well known Canadian tech school (now in professional school in Canada). I usually would skip the last few weeks of school and study straight through at the library. Studying ten hours a day instead of going to class worked for me. Studying for exams is boring. It's easy to get distracted. I started off timing myself with my watch on seven hour countdown. Every time I got up or got distracted I would stop the clock. Builds good habits and after a while you won't need the countdown and you'll gradually be able to study more hours a day. 12 to 12... Studying is a pretty individual thing but that's what worked for me.
