Gen chem 1st year, bio second year, orgo/physics 3rd year together (along with mcat prep for april mcat). Labs were taken concurrently with my classes.
Freshman year: Phys I and II; Calc I and II; Chem I; Bio I. English (2 terms).
After graduation (while working full time):
Summer: Orgo I
Fall: Advanced bio classes
Spring: Orgo II, MCAT
Summer: Orgo lab
Fall: gen chem I lab
Spring: gen chem II lab
freshman:
fall: gen chem/lab, calc ii
spring: gen chem ii/lab ii, bio i
soph:
fall: orgo i, bio ii
spring: orgo ii/lab
jr:
fall: physics i/lab
spring: physics ii/lab
Freshman: Physics I, Gen Chem I and II, Calc I and II
Sophmore: Physics II, Bio I + II (condensed into one semester)
Junior: Upper level Bio, Orgo I
Senior: Orgo II, MCAT (same semester actually)
Post-grad 1: Biochem I
I wasn't pre-med until my junior year, hence the late orgo. The rest was required by my major.
