I am computer science master's student. I love computer science but don't want it as my career. Is it possible for me to get into medical school now. I have not taken any biology, organic chemistry or inorganic chemistry courses in my undergrad. As most medical school require, pre-requisite courses, where can I take these course. Is it possible to get into a school, study those courses for a semester or a year and then go to medical school. (I mean are there any medical schools that allow student to go through prerequisite courses after admission).
Ahh computer science. When they have to put the word "science" in the title, there is no science in the program (social science, political science, etc). If you are missing even general chemistry, here is a typical fast path to medical school:
Summer year X: take all of gen chem
Fall year X: start bio / physics / organic
Spring year X+1: finish bio / physics / organic
Summer year X+1: MCAT, apply
Fall year X+1: interviews
Spring year X+2: finish interviews, decide on school
Summer year X+2: party, finish bucket list, etc
Fall year X+2: begin medical school
Unfortunately you posted this in August of 2014, so you've already missed the window for X=2014. The fact that general chemistry is a prereq for organic chemistry is going to really control your schedule, however you work it.
