depends.. if you take time off, make sure you are the type that won't have to overcome inertia to get back into study mode. Maybe better just to take a lesser load of classes and get some PE classes like diving, sailing, volleyball etc..

What is a waste of time generally is going to classes. If you are bright, then read the book and associated materials. Find out what exams are like for each prof.
Just take exams and ace them. assuming class attendance is not part of the grade.

stick with it. You may not end up making a living with what your degree is but the diploma makes a big difference in the job market and your profile later.
