As someone who shoots for an A, i have my work cut out for me. Its a lot of time planning though. I probably stay up until 1:00a.m. studying and such, but that doesn't keep me from going out with friends for dinner or having some good times. (I wake up pretty late tho.. Its a bad habit.. :/)You just can't waste time when studying. Manage your time and come up with a realistic approach to tackling the workload. Yes, some days you'll have to miss out, but if that means an A vs. a C on a test, I believe it is well worth it. If you want free time, you'll find it easily at the expense of retention of info and competency
