I’ve been in your situation before! The best thing to do is to maximize productivity. Set aside at least 4 hours a day for studying, organizing notes, completing assignments etc. 2 for A/P and 2 for micro. I recommend the pomodoro technique to minimize burnout. I had classes in the morning so after class I would give myself 2 hours to relax, watch TV etc and then faithfully at 4pm I would study for 4 hours.
