<p>total units (waitlisted + enrolled classes) must be 19.5 units or lower. then it gets raised to 22 (waitlisted + enrolled) on the first day of classes (which i think is like sept 25). i suggest waitlisting, but if you end up not getting in, to enroll in a low-priority class (one that you're pretty sure won't fill up...such as many humanities/arts classes)</p>
<p>if A and B are 300 person classes where you don't sign up for a specific discussion, if you waitlist between #1-20, you're guaranteed to get in. maybe even 21-50 but it depends on the class.</p>
<p>if they are 300 person classes where you DO have to sign up for a specific discussion (such as a lot of "mini" classes of 30 students), then you will get in if you're #1-3 or so. after that, it's not as easy.</p>
<p>yes, no one will care because no one will take attendance (for 95% of classes) you just sign up via webreg and just add the class like you would regularly.</p>
<p>lecture's in a lecture hall, presided over by the professor, everyone enrolled in the lecture goes to lecture together (can approach 400 kids in warren lecture hall).</p>
<p>discussion's held in a smaller room, usually max of 35 students, it's run by a TA to go over lecture topics, homework problems, give quizzes, whatever.</p>
<p>well for example, say you waitlist for a class and you're #10 now.</p>
<p>well, if you wait until the first day of classes to sign up for the class, you might be #30 on the waitlist. signing up on the first day does not guarantee a seat in the class itself.</p>
