Exchange

I'll take the TOEFL exam in two weeks. I'd like to get a mark as high as possible but it's not like I speak English fluently.
But the fact is that I may be lucky enough to get into an Korean or an Japanese university as an exchange student next year. And for it to happen, I need to get a very good score!!
Please tell me if I make any mistakes.
The more I think about it the more I want to go overseas. Being far from one's family, not speaking the local language but English. I know about it.
I really want to try living one year abroad on my own and see how really this foreign country is.
I really like Paris and I like studying in Nanterre but I just want to go to Asia.
Would I like it?
