I got an okay from my sister to mention her school. She is at Harvard Extension. With two classes a semester - 8 credits - she and her friends spend all their time doing homework, especially Physics with one Rueckner teaching them. ALL THEIR TIME doing homework. And they hardly ever get A's, although they do magnificently on the MCAT's. Unfortunately, because of the bad grades at Harvard Extension, the % of people who do get into medical school after Harvard Extension is very low - about the same % as anywhere else (Source: Dr. Fixsen's video talk). My sister and her friends barely have time for volunteering and stuff like that. In contrast, in the 4.0 thread, students seem to be taking 19 credits in very challenging subjects like Biochemistry, Biostatistics and other equally challenging subjects in a single semester. It is a little confusing to me how they manage that in ONE freakin semester.
