I’d wait until M10 for sure for exactly the reasons you cite. Lord help you if you or DD falls for a school and then M10 brings devastation (for the record that’s not going to happen!)
Also…the eternal optimist in me (ha) says the zoom classes share little in common with in-person classes and so to the extent I hope we’re in class in September I’m not sure I want to get too wrapped in whether a teacher is a zoom star.
