Student Exchange Programs

During my Junior or Senior year, my parents (( who are divorced )) have decided to let me go to Japan as a foreign exchange student. But before I am assured that I will be qualified, I want to know what I need to have before I can qualify. What grades do I need? What do I take? Things like that.

I will do 2-3 years of Japanese tutoring before I go, so I can talk to the people around me.

+If I go during Junior year, I will stay un till Senior year, just visiting during summer break. I will come back when I am 18 and live in an apartment with my friend and attend College to become a doctor. (( Or just be lazy and do Japanese tutoring and classes. ))
