I'm in a bit of a tough situation.
I want to be able to start medical school by fall 2011 (I'm a non-trad, currently 29 yo), which means that I would want the AMCAS app to go out in June 2010, which is just a little over a year away. I still have to take 3 quarters of Organic Chem as well as a few quarters of bio and physics. I could easily finish all these prereqs before fall 2011, but since I work full-time I think it would be pushing it to try to complete them before June 2010.
So the question is: do medical schools require that all the science prereqs be completed before the app is sent out, or is it okay to not have all science prereqs completed just as long as they are done before matriculating?
