How to transfer?

First ask your current class teacher. He should tell you to go to your old school to find your old teacher. Maybe you don't have a good relationship with the old teacher, but you must go. It may be that the original teacher was better and smoother, but it may also be more difficult. It doesn't matter. Just ask your class teacher to set up one in your current school. There must be a jump in the middle. In short, just ask the teacher how to do it and you will do it. Finally, I wish you good luck in your study.
