<p>Next semester I'm thinking about taking Physics 125/127, English 125, Clarch 222 (Intro to Roman Archaeology), and either Bio 172/173 or Chem 230. I'm a pre-med freshman btw.</p>
<p>Could someone who took / knows about either Bio 172/173 or Chem 230 tell me how difficult each one is? Also, how much of Gen Chem are you required to remember for Chem 230? Thanks</p>
