After taking several years off after completing my prereqs, I discovered that many schools either require or strongly recommend a Biochemistry course. Well, it can be quite difficult to find one when you're not in college anymore. Community colleges don't offer it (at least not here), and other universities often have a lab component which I just don't have time for. Well, I finally found a course through UC Berkeley Extension called X105 Introductory Biochemistry. It's a 3 unit at home course, and then I take proctored final exam. I thought the final had to be taken at Berkeley but as I look through the course notes it seems as though you can take it elsewhere if you don't live in the area. Anyway, I just thought I'd bring it to people's attention in case they are needing a Biochem class for Mayo, Mich, Irvine, USC, etc... or if they just want to learn some Biochem before med school. At first glance the course doesn't look all that advanced or great, but at least it will satisfy my requirement. Good luck!
