I didn't notice an available date on the app when I filled it out, but that may have changed. When I interviewed, they asked if I had any questions. I mentioned that if they were to extend me a job offer, I would greatly appreciate if they were able to give me a class date a few months in the future for personal reasons. They were happy that I mentioned that, and even happier to accommodate me. They said that the only restriction was that the class they offered couldn't be more than 6 months after your interview.
