The best place to find info about courses is on the Time Schedule.
Make sure you scroll down to Graduate Time Schedule.
If you want to know which courses are offered this academic year, click on 2017-18 Autumn-Spring which will lead you to this page:
This page lists the different Graduate programs. If you are looking for an EDU course, click on Education (EDU) and that will take you to the 2017-2018 Education (EDU) Course Offerings page:
This page includes all EDU courses with information such as course title, course reference number (CRN), instructor, day(s) and time the course occurs, start & end dates of the course, and number of open seats.
If you click Course Details next to the title of a course, you will see an expanded explanation of the course as well as any course restrictions:
Course Restrictions will tell you if that course is restricted to specific programs. For example, EDU 6030 above lists Restrictions: Master of Arts in Teaching majors only. Graduate only. So that course may only be taken by a Master of Arts in Teaching (MAT) Graduate.
Some courses may have multiple offerings, multiple restrictions, and different restrictions depending on the quarter, so be sure to always check the restrictions if you are unsure of which course CRN you need to register for.
