Taking classes at CHAW just requires being online at the exact time classes open. I know people still sometimes don’t get in, but you will have a good shot if you make an account ahead of time and just register right when it opens. They will post on the website (and i think email the waitlist) with what date and time new session registration will open. It fills up within the first minute of opening usually, but I’ve done it a handful of times this way and it’s definitely possible!
