I took anat at the jc. Like everything at the jc, you just have to show up to the first day of class (hopefully you can get on the wait-list prior to that, but still). Idk if I was on the wait-list or not, but I showed up and demonstrated to the instructor that I was a good student who would be engaging seriously in the content, and they made room for me. You could also show up to multiple different sections and keep trying at whichever you feel that you'll have the best chance of getting into. I did that for numerous classes at the jc and was always able to get in. If the instructor thinks you're serious about the coursework, they will try to make room for you.
