More lecture seats than lab seats?

Hello!
So I just transfered from Pasadena city college to CSUN. While registering for classes, I noticed that there are way more lecture and discussion seats than lab seats. I’m not familiar with how this works.
It appears that I can’t add only the lec and discussion as I need to have the lab course in my cart as well.
Back at cc, if the class is full, then students can test their luck and sit-in kn the first few lectures and maybe get an add code. Will I be able to do that here at CSUN? There is no waiting list available. This is a chem 101a/l

Thank you in advance for any pointers and clarification!

Im pretty sure youre allowed to do that if the professor lets you. Depends on the professor though.

How in the world did you get that early of a registration date! Major? Did you transfer with an aa-t/as-t? I’m also a pcc transfer student, however, my date was 7/11 @ 2pm. I didn’t get any core classes. Any augesstions?
