You can transfer to another school, but you must first submit an application in your school, and then go to the education department where your school is now located to find someone to approve it. If it is inter-provincial, you may have to go to the provincial education department where the school you want to go is located! Of course, if you want to transfer, you must be admitted to the school you want to transfer to. However, it takes a lot of time and energy to have a certain relationship.
