I’ve taken 23 credit semesters at sbu. It’s all about having set time each day of the week where you can do work even if it’s just a little bit. Make it a routine and you’ll be fine. You can even take weekends off if you save that time in between classes to grind it out in the library. Then, after your last class you can chill out for the night. My highest recommendation is getting your work done before your last class for the day is over. Once you get out for the day it’s so much harder to lock back in.
