IMO as long as you make an effort to seek help from your professors in all of the classes you're having problems in, that is to say you actually go when they have their scheduled office hours so that they can figure out how to get you to understand what they are teaching; after all it is their job to be able to explain the material. Then at the very minimum you should pass the classes and eventually have what all deep thinkers all over the world have, a diploma.

If it's at all possible for you to get through college without going into debt with student loans then stick it out. And make the professors do their job by transmitting their knowledge in such a way that you understand it, and again the best way is to see them during their office hours. This way if you come up a little short on the exams they'll remember you and give a passing score (that's where pass/no pass can help out a lot if it's offered) Seriously I used that strategy myself in a couple of classes that I needed to pass and it worked.
