<p>Hello, I was wondering, is it important to take Chem 20L at the same time as Chem 20B? Or can it be taken the next quarter, while taking Chem 30A? And would this delay my graduation? This is because the class is closed, so I can't get in. Thanks</p>
<p>It’s not too terribly important for continuing the Chemistry series, of course, this depends on your major. Like, if you’re a Chemistry major, you’re about on track so long as you take 30A and labs for it or before around spring quarter, give or take one quarter. (Though the sooner the better. Cause like 30A and the labs aren’t offered certain quarters. Check UCLA Chem dept. schedule online. I believe it’s listed under Undergraduate Student Handbook)</p>
