<p>Hey, Does anyone know whether Chem 20B/20L is a difficult class or any thoughts on it?</p>
<p>It was relatively simple (compared to some other classes such as 20A). 20B is just a bunch of themodynamic and gas law formula memorizing along with some concepts. 20L labs are easy; they're pretty much like high school labs but sort of more sophisticated. A lot of them involved titrations. The hardest part of it all was probably the lengthy and numberous write-ups.</p>
