I just registered for classes this morning, and I couldn't get into 2 of the courses I need for my major.

I'm not technically a computer science major, just a "pre computer science" major, and I'm finishing up one of the prequisites this semester, so the system won't let me enroll. The thing is, I submitted my form to change to a full computer science major last week, and I know I have hit all the requirements to do so, and I also know that I will finish the other perquisite course with a good grade. Either way, I can't tell that to the system. So I email the department as we are supposed to do when something like this happens, and I wait. I just checked the courses I'm trying to get into again, one hour later, and I see that they've been filled up. Lovely. Even though I've technically met all the requirements to enroll in those courses, I couldn't get into them.

I'm super frustrated about it and really stressed about not graduating in 4 years. I know that it's not abnormal to take a couple extra semesters, but I feel so bad for my parents, since they're the ones paying for my school. I've been stressed about this exact scenario happening for the past few weeks, and it went down exactly as I expected it to :/
