First day of class registration?

When do Barrett’s and regular class registrations start? I’m a mech engineer major so if I sign up the same hour regular is open, what are the chances that I get all the first year classes locked-down, or do Barrett’s people usually fill all the good classes. Assuming I get into Barrett’s the only reason I’ll think about attending is to get priority over classes.

Are you a freshman? All freshmen pick their classes at orientation so you’d just want to get into the earliest classes. I am a comp sci major and went to the March 22 orientation (non-Barrett), everything was available and I got in all of the classes I’d like. Many major specific classes are set (time and day) in your “block” and there are spots reserved so you’ll get those. My best advice would be to go to the earliest orientation you can.

Are students allowed to change their campus choice (polytechnic/tempe/west)

@california2018 - that would imply a change in major. If so, then you need to contact your advisor for advice. My son changed majors between orientation and move-in with no problem. But, that was not a campus change. An advisor will be your best source for this information.
