I had to stay in town but tried to go to the best university around. Studied three subjects, computer sci, math and economics, so I can learn as much as I can in terms of sciences and business ... it took me 5 years to finish it with the jobs I had ... for the first two years my grades varied I had good ones and bad ones (mostly Bs) ... but for the next three years I mostly got As specially on courses that mattered the most to me. I also did an internship at a biotech company in Germany, worked with SAP for my university, got hired by one of my professors and helped him to write a book on astronomy, did a project with another professor on Six Sigma, and another project with a different professor on databases, worked at a gaming company (mostly R&D) and did a few other projects on the side. Thats mostly what I did during school ... but then graduated and decided to start my own company, which I did, and learned maybe more than ever ... and am now working on another project .... so I am also not too clear about your question ... but what you want to do after college is also important, meaning if you want to do masters then you must try to get good grades, if you want to get a job then it depends on what kind of a job ... but as a general rule I would say try to do your best ... if you don't do too well at the beginning try to pick it up and do better later on, people will notice that, they like to see you improve, specially during your senior years ... the better you do the more options you leave open for yourself. I think undergrad mostly fills you up with the basics, so you can go and specialize on whatever you like after. But the most important thing you can take away from school is getting disciplined, and learning how to look for information and learn more when you need to. Getting good grades also means you have actually learned something from college. The worst is to go to college and get bad grades and the excuse being "my courses are boring," or something along those lines. Your marks might not be that important to everyone, but what you did with your life within those years would matter a lot to anyone that might be interested in you. I don't mind when I hear people drop out and end up doing something, even if they don't make it big. At least they realized they don't want to waste their time with school and they have other ways of doing it. Bottom line, having good grades will never hurt you no matter what you want to do. But if you don't have good grades then you must have other stuff to make up for it, or to replace it and sometimes you need to give a valid reason of why you don't have the grades. Just remember that nothing is the final answer, and there is not one way that you can do it. Get creative and come up with other ways that can prove yourself.
