<p>First, how much more difficult is the 20 series compared with the 14 series?</p>
<p>I am a Phy Sci major currently enrolled in Chem 20AH.
Took 20 series cuz I wanted to learn more about chem and wasn't sure if I might switch to engineering or biochem later.</p>
<p>Secondly, I have Chem 20AH with Baugh, and Bruinwalk reviews say that he's terrible and that I should avoid him at all costs.</p>
<p>I'm thinking that I might drop his class and take 14A next quarter. Should I do this?</p>
