<p>Does anyone know if the chem3bl lecture is necessary to attend? I have this class that I really want to sign up for but conflict with the 3bl lecture time. I already took 3b awhile back but just never took the lab portion.. I heard that chem 3bl has been changed and there's a final now.. can anyone explain the course format for 3bl?? Thanks!!!!</p>
<p>i wonder too.</p>
<p>My friend who has taken both said that 3AL was useless, but 3BL was pretty important because you learn a lot more about NMR.</p>
<p>Viernes is pretty good at explaining the NMR/chromatography techniques. The stuff he lectures on definitely shows up on quizzes and the final.</p>
