Even if you have a medical cases it won't work out. I tried to change when I was third year. My reason behind it was I got badly sick. The next year I presented a medical paper referring that I can't go back to where I was because of my health issues. They puted a criteria for a student to be transferred from another campus..the one thing they said that made me not to be transferred was that I was not active, means in order to be transferred you must report while you are learning. If not you can't (what they said). And this is reason that prevented me from switching. If you are really in to it. You gotta find relatives someone who works as a teacher or a member of stuff. Or if you have cash throw some. cause these days everything is about relative and money.
