The typical track is fundamental bio (darwin,plant,eco,animal div) with gen chem 1 (stoich, sigs, lewis, enthalpy) for the 1st semester. 2nd semester chem 2 (thermo) and bio 2 (cell, intro molecular and biochem).
For second year second semester you need chem 1.
BIO 1 doesnt really go into too much chemical explanation as much as Bio 2. Play your strengths, Keau
