There are two important sites related to enrollment at Berkeley:

• http://schedule.berkeley.edu is the course catalog
• http://telebears.berkeley.edu lets you sign up for courses

You have until the end of the third week of classes to set your course enrollment for the semester. It's helpful for the professors if you enroll sooner rather than later, however.

Unless you have made arrangements otherwise, you need to enroll in 201, 290A, and 300 (if you are GSIing). You should be enrolled in at least 12 units of classes. The usual way to achieve this is to take the aforementioned classes, one further “real” graduate class (218, C249, 250, or 252) and a seminar or two. The seminar courses have no requirements beyond your attendance at the weekly meetings.

These are offered every semester.
