My schedule so far, need help deciding a 4th class

<p>So originally here's what I wanted:
CAT1
MATH20B
CSE8A
CSE91</p>

<p>I got the first 3, but I didn't realize how much CSE91 would fill up and I'm position 37 on the waitlist. So instead, I'm considering PHYS2A because it's supposed to be taken concurrently with MATH20B, but I'm scared 15 units will be too much of a workload for a first quarter freshman. My advisor suggested either physics or a GE (my major is Computer Science) but I couldn't find any GEs that didn't have any prerequisites, were on my audit, and were offered this Fall. I might be missing something, does anyone have any advice?</p>

<p>You need to take CSE 8AL with CSE 8A</p>

<p>Oh wait is that required?? That sounds a lot simpler and more fun, should that be my fourth then instead of CSE91 or whatever else?</p>
