I guess maybe some more context would help. I decided to become pre-med in the middle of spring my senior year of college (2008), so I didn't exactly have a lot of time to take all of the courses covered on the MCAT. I took a year (including summer classes) of the med school pre-reqs in the 08-09 year, and then the MCAT this summer so I could apply for 2010. I wanted to take orgo II this summer, but it isn't offered. If I waited till I had taken orgo II this fall, I would've had a year and a half to waste, as I already have nothing to take this coming spring.
So the point is that I couldn't have taken the MCAT after organic II unless I wanted to have this spring and the entire next year with nothing to do.
I'm sure someone will suggest this, so I'll shoot it down now: I am broke and can't afford to travel. (I graduated, which means I have to pay back my student loans, and my job at the hospital pays me about $7.60/hr. ...not exactly great wages.)
