I took 18credit hours or 4 classes at college and studied less than i do now.I'm not going to say it's easy but we've only lost 6 students in the first term and the second is about to start. You study alot but i've found that i have class four days aweek and normally three tests aweek. I read all my notes everyday and study late on the week ends plus don't forget we have study groups on test days before school and trust me this is the key teamwork with classmates. You will loose alot of free time now but worth it in the long run. Good Luck if you want it bad enough you can do it.
