<p>I'm planning to take Math 31B, Chem 20B, Chem 20L, and some GE next quarter... My first pass is on the 19th so I have to choose which 2 classes I'm going to sign up for wisely. My question is do classes like Math or Chem usually fill up by the first pass? There's only one good professor for Chem 20B so i really need to get him... Do you think I'd be able to get him with my first pass? Which classes should I sign up for on my first pass?</p>
<p>For sure, sign up for 20L first. (If URSA won’t let you sign up, enroll in 20B first, then 20L, then drop 20B.) Labs always go the quickest because of the limited space and the fact that they will not over-enroll.</p>
<p>About 31B and 20B, I would say the classes fill up about the same. Though I’m inclined to lean that 31B would fill up faster since 20B is not required by as many majors. If you want a good Chem professor, do 20B in your first pass though.</p>
<p>(Besides, if you don’t get into math, someone WILL drop. It always happens.)</p>
<p>Check on the 18th to see how full each class is. Then make your judgement.</p>
