I finally went today and timed myself walking from one class to another (the ones on the opposite of the campus) and out of the 15 minutes I have in between 2 of my classes, it took me 12 minutes to walk. I don't think its enough time, so I just switched one of my classes to tuesdays and thursdays instead of MW. That way I don't have to run to get to any classes, and I have plenty of time to get to each. I have 2 hour lunch periods, in which I could also go to the computer lab or something in the library which would be really nice. Or catch up on some homework. I think this is the best option.
