When I registered for my courses it never gave me an option for what times I want my tutorials. Is that normal?

Yeh, don't worry. You only had to choose the courses right now. Solar will be opening up again on August 10th, 8:30 am (if you've completed the payment agreement). If you haven't completed the payment agreement then August 15th, 8:30 am.

A timetable will be released for you on August 8th. On August 10th/15th you'll have the opportunity to change around the times of your classes/tutorials/labs if you do not like the way they are placed.

So many threads made for the exact same question

So I didn't get a class that I need, and I just went back on SOLAR to see if it was available yet, it has one option available but when I click it, it has the cores and tutorials full? Do you think it'll change?

As has been stated in at least 10 other threads, just keep checking back, or contact the student advisors.
