Wow... how did I miss that??
Lol, thanks for pointing that out!!! I did send BUSM a message, this was their reply:
"Please do not double count courses on the grid. Put biochemistry in the biochemistry section (I asked if biochem would go under "Biochem" or both "Biochem" and "Biology"). If your courses exceed 20 please explain below the grid. In the preferred institution section only put courses from a 4 year college."
But it says in the instructions:
If your undergraduate institution uses a quarter system, convert to semesters using the following ratio: 3 quarters = 2 semesters. If your calculation is not a whole number, round up and explain this in the space below the grid.
