I used to feel the same way about college. The thing is, the majority of undergraduate courses are not interesting and for an intelligent person a lot of the time spent in them is wasted. I view them as hoops that you need to jump through to get your college degree, which I believe is worth it. I don't think there's a way to make them interesting - you just have to get through them.
To improve your college experience, figure out what you want to do with your time outside of class. Specifically, I would look at what professors are doing, whether inside your department or not. Smart, successful professors solve interesting problems, and those problems may or may not be interesting to you if you take a shot at them. See if you can sign on as a part time employee - professors that are doing well often have grant money that can support something like this. Programming knowledge really helps, especially in departments where programming knowledge isn't common.
If you spend some time in a research group and find it dreadful, it's easy to duck out and try another. Try and find people who will pay you something and give you a degree of independence, and give it a month or two - see if it's something you can see continuing to work on.
I view this - not what classes you take or your grades, but what you do - as the important part of college. If you can keep up decent, 3.0+ grades, but have worked on interesting things, it looks much better to future employers/grad school admission committees/coworkers than if you get that 4.0.
