It's impossible for anyone to really answer that question for you. However, I think you are ahead of most college students in that you asked the question at all. You might look for ways to either better your school experience, or avoid the either/or choice. Perhaps find or start a club that meets regularly to discuss business ideas. If you do leave school, at least make a visit to the registrar's office and file a leave of absense, claiming economic hardship or whatever, so you can easily return in a year or two if necessary. Perhaps you can come up with a business project you can work on while taking the minimum necessary number of hours. I have heard that grades and completing college do not correlate well with various measures of life success (apparently high school grades and completion do). I have also heard that dropping out with straight A's is one of the best predictors of future success. That makes sense to me, although I can't say which way the causal relationship goes; but I would not neglect the grades even if you plan to leave. You might put some energy and effort into finding classes you think will be worthwhile. Often various bureaucratic requirements of being in a certain major or pre-requisites can be waived by petition or lobbying the professor. If you truely feel you are wasting your time, leave in an organized, purposeful fashion. Let the school know, preserve the ability to come back if that is easy, preserve your fraternal network and other friends by letting them know and maintaining contact. As you begin to tell professors and friends that you feel you are wasting your time and are leaving, you may find opportunities at school open up, or that you get tips to interesting places to work.
