If you are a graduate student who wants to enroll in a graduate class, and you can do so, then just go online to MyUCLA and enroll. If you can't, perhaps because the class is full, you must express your interest using this form. (You should be somewhere else if you're an undergrad or if you're a grad student wanting an undergraduate class.)
We've set up this form so that you can tell us what your preferences for grad classes are now, before the quarter starts, so we can make plans to try to accommodate you. The sooner you fill out this form, the better the planning we can do to accommodate as many people as we can. Although CS 201 is, of course, a graduate class, for the purpose of this form, let's consider it not to be.
Our accepting this form is not a promise you'll get in; it's merely a way for us to measure demand. We are collecting your email address, so we will contact you when there's relevant news to report. Essentially, we're asking you to please leave us alone — if it were just you (singular), we wouldn't have to say that, but you (singular) wouldn't believe how many of you (plural) there are, flooding instructors' mailboxes with similar messages. It might not be until the end of the first full week of the quarter that we issue actual PTEs.
If your desires change after submitting this form, submit it again with your new preferences; a later submission replaces an earlier one.
