So, college is starting back up
Get to know your professors and go to them when issues arise.
I highlight this one because I didnt do it when I was in college and wish I had.
If for no other reason, you may very well need a recommendation of some kind coming out of school, either for a job, or grad school, or both, from one of your professors.
If you went to a big school and never sought out a professor, or never had a smaller seminar type class as an upperclassman, you may find yourself as a senior knocking on the door of the English prof who taught your freshman English Romantic Poetry seminar who gave you an A and reintroducing yourself, asking him for a recommendation.
This is not the best approach.
