I want to reject my former tutor and go to another school. The main points of a specific letter ~

It's best not to write letters. I feel that many things are hard to say clearly when writing letters. It is best to talk with the teacher in person or by phone, mainly explaining why you want to change your tutor. Your idea is sincere, you'd better not perfunctory, which really makes him feel that you have no choice. He is well thought out. As long as this is the case, he usually doesn't have any ideas.

What you need to make sure now is whether other schools must have you. This is very important. Don't let both sides can't solve it by then. Before refusing, you'd better make sure that the other person is the teacher you want.
