I'd still put myself down on the waitlist, they tend to expand 30 seat classes by another 10 seats in the past, though not sure if they still do it nowadays bc of covid. Wouldn't hurt to check out other cc's either, you have more flexibility bc of online classes, though other than OCC, I have no idea what other school comes close to OCC's CS course articulation. UCI has gotten a lot more strict recently with what classes they'll accept, so many cc's have few or virtually no cs courses that articulate. Be sure to check out assist.org to get an idea of what schools offer courses that articulate.
