How did you get a high gpa in college/university?

In addition to going to classes, I would allocate time everyday for studying or homework. I scheduled 2 to 3 hours everyday and kept to it like a job or something that you could not blow off. After a while, it became automatic and I just started doing it everyday. You would be amazed how much you can accomplish when you get organized and stick to it.

To be honest the key in undergrad is just going to class. I can imagine anybody making lower than a B if they went to class everyday. The trick is just to go to every class, keep up with your reading. Thats important, its way easier to retain it if you keep on top of your reading schedule, and just do your assignments on time and study for your tests. Undergrad is easy to get a high GPA with minimal effort if you just go to class and take care of business rather than put it off.

be a good student, do your homework, study, attend classes. pretty much like high school, except you're more free.
