Without going to every individual university's web site, how can I find out which universities on the West Coast and in the Midwest offer 4 credit classes rather than 3 credit classes? My university's Summer classes are too expensive for me, so I have decided to spend summers on some other not-as-expensive campus. But I need universities offering 4-credit classes rather than 3-credit classes. Any ideas or specific suggestions?
Thank you!
