I have only 6 more weeks until I graduate high school, and I want to know when I get to pick my classes for the Fall term 2015. You’ll be much appreciated for answering!
Did you sign up for Freshman Orientation? This is when you usually sign up for Fall classes with help from a major advisor.
Thank you for answering 
Sign up for mandatory new student orientation starts July 1st. Do I give the major advisor a call or will I get to meet them on orientation day?
Every UC is different, but they usually will split out Freshman into groups and you get to meet with a peer advisor whom will help you figure out your classes and help you register. I am going off based on my experience with my son’s (neither attending UCLA), but most orientations are similar. Once you sign up for orientation. they will have a schedule of events/activities that you will be attending to help with your introduction into the University. You can go onto the UCLA website now and check the course catalog, just so you are familar with some of the classes you will need to take the first year and get some ideas about possible GE’s and pre-reqs. If you are planning to attend orientation, there would be no reason to contact an advisor.
