Class capacity for computer science courses

This is my first post on CC, so please excuse me if I posted this in the wrong section.

I will be majoring in computer science when I transfer to the U of A this fall as a transfer freshman. Being that I can’t register for any classes until June, I’m concerned that the classes I need will fill up. I checked today, and two of the courses I need are already at 1/3 to 1/2 of the way filled up.

The courses I need to take are:
- Digital Design
- Programming Foundations I
- Calculus II

Do these courses typically reach capacity and have long waiting lists, or am I just being paranoid?
Thanks in advance for helping me out. :slight_smile:
