I’m experiencing this as well. I’ve gotten into a couple T20s already but I was shut out by most of my match schools. One thing to note is that colleges are looking to keep their yield rate high. If they think you won’t go, then they will most likely waitlist or reject you. In addition, as mentioned by @lookingforward , colleges have a different set of criteria that they want. It is very possible that you fit some of the more competitive schools and not so much the non competitive ones.
