Many questions, few answers. Here we go...
Premedical courses are defined as:
One year of Biology
One year of Physics
One year of English
Two years of chemistry (through Organic Chemistry)
(Taken from the AAMC website:
http://www.aamc.org/students/applying/about/start.htm)
Some medical schools have a mathematics requirement as well.
Alternatively, you could make high grades in the required courses and not worry about needing to boost your BCPM GPA.
You can find it here (SDN), the AMCAS website (
http://www.aamc.org/students/amcas/amcas2009instructionmanual072808.pdf Page 14, discusses a BCPM GPA (Biology, Chemistry, Mathematics, Physics GPA, and an AO GPA (All Other Courses GPA), and the AACOM website (
http://publish.aacom.org/Pages/default.aspx I don't remember exactly where on the website).
I know that. As long as the courses are college courses (not AP, CLEP, IB, etc) then the courses will count as part of your BCPM GPA.
Difficulty level of remedical courses in not a factor. Some universities will not count remedial courses toward a degree. Not everyone needs to take remedial courses. Medical schools will count courses that are part of the BCPM or AO GPA. Course level does not matter.
