BIOL 102/3.0 and BIOL 103/3.0 (Biology: see What BIOL course should I take?)
CHEM 112/6.0 (see first year Chemistry)
MATH 121/6.0
PHYS 117/6.0 or PHYS 106/6.0 or PHYS 104/6.0 (Physics: see What PHYS course should I take?)
Although Physics is not required for the Minor or General Plans, if you don’t take first year physics, and you change your mind, you will find it much harder to change to a Chemistry, Geology or a Life Science Plan in the future.
