Are classes guaranteed?

Like most of you I’m really new to this haha, I don’t know if I did this right. I’m in engineering so my classes are pretty cut out for me (1 math, 1 science and 1 intro course (CS or ENRG) or 0 science and 2 intro courses, engineering seminar, physical education). So I was able to get the following courses:

Multivariable Calc 1920
Chem 2150 w/ Lab
CS Intro to Python
PE Wellness and Fitness
Engineering Seminar once a week
Still have to submit Ballot for writing

I think this is around 15 credits, and I was lucky and most of my classes end around 12 pm save for the 3 hour lab and 1 discussion for CS. Still, how does the preenroll work after this? Am I guaranteed to these classes now? I understand there’s Add/Drop in August to make changes but I want to make sure that this schedule is secure. My AP scores have not yet been added to my student center either. I followed the steps the website gave (1. select class, add to cart, enroll (verified by a message “this has been added to your enrollment schedule”)), so am I now enrolled in these classe? THANKS A TON.

Yep, if you enrolled in them then you’re all set! If you log into student center you should be able to view your schedule either as a list or in a calendar format.
