Basing off the U of C listed courses...
BIOL 305 sounds easy. It sounds like Bio 30 and then a little on top
BIOL 307 sounds similar difficulty but goes in a different direction. Nice easy prerequisite too (just be in 3rd or 4th year)
CHEM 301 sounds really easy.
If you're into a little math, PHYS 303 might work.
