School starts tomorrow

I have been out for a few years I have it approved by the school system that teachers can call me by my preferred name but last year there were still a couple teachers refusing and getting upset when I corrected them. Plus even with a couple of the teachers calling me by my preferred name the majority of the students don't does anyone has any tips to either pass more so than the teachers feel more comfortable calling me by my preferred name or any tips on how to get peers to be more accepting?
