<p>I'm currently signed up for both 9-1 on different days, but I might have an internship 30 min away at 1:30. Do labs generally take the whole 4 hours? I remember chem 3A usually took 3 hours, but I wanted to be safe and check. Thanks!</p>
<p>Usually, you’ll be able to finish at least half an hour early, but there may be one or two days where you have to stay the whole time. I would talk to your internship about how you have a class right before so you might be slightly late.</p>
