What level of adult learn to skate should I take?

Hello! I’m 19F and have been skating on and off for about a year now. At my college last year, I did a figure skating club where I learned a lot, however, we were not taught much technique. For example, I can do backward crossovers pretty well but I’m not well trained in inside and outside edges. I want to get more into skating but I’m not sure which level to sign up for. I was thinking maybe adult 4 or 5? Let me know some advice!
