<p>So I'm registered for Chem lab from 8-12, and the math class that I want is from 8-9:30. Would it be wise to stay signed up for chem lab but go to a different lab section at a different time, or would it be better to forget math and take a different class? Thanks. Both classes are early as hell but they're only 2 days a week, and the other 3 days are late starts.</p>
<p>they'll kick you out of impacted classes like chem 1a, 3a, 3b if you don't show up to lab the first few sections.</p>
<p>but can I switch lab sections by just showing up to a different one? I don't really have time to ask the professor because registration ends in 12 hours.</p>
<p>no, if you're not waitlisted, you essentially have no chance of getting in. in 1a, 3a, 3b, the profs and gsi's don't even handle scheduling changes. there's a designated person who takes care of it (possibly head gsi sometimes), and they'll give you the name and their open office hours the first day of class.</p>
