I found a new source for 300/400 level biology courses. The University of Maryland University College has many for fall! For someone at TESC seeking the Natural Science and Math degree under the new rules, this is a good find! Enjoy! Online Schedule of Classes and Catalogs - UMUC
Very cool, thanks! As an aside, $512/credit (tuition + technology fee) for undergraduate courses seems insane to me!
The course list looks interesting, but some similar courses are available for less from UCal Berkeley extension for slightly more than half the price. Empire State College also has several upper level biology courses, although there doesn't seem to be any overlap in content with those offered by UMUC.
It is expensive. That specific degree at TESC was changed making it very expensive and difficult to complete. I believe it's probably geared toward people with existing upper level science or math credit.
