How do college studenrs who go out to bars every night/frat parties do well in class?

I work at a bar and out most every night also. It's really all about time management, actually learning the info for the class, having friends sign you into class, and getting help from people who had class in past. Just take hour to two out day for classes needing to study for and focus on them. Most classes though such as English, Maths up to Calculus and sciences already learned before in middle and high school so those are just retakes pretty much. If did well in highschool and remember stuff from than that helps.
