That's why I'm studying English

Last year, I have discovered a thing (that should would make real my greatest dream) that would make my biggest dream come true: a scholarship called Monbukagakusho, that offers me the chance to graduate in Japan!!!
I'm really anxious about the test, that will happen in a few months, especially because there's an interview entirely in English!!! I think I can read and understand whatever could be is written in English, but I'm not sure if I can catch someone's words in this language. Besides that, the Math, Physics and Chemical tests are made done in English, too, what turns which makes this language even more important to me if since I really wanna want to study in Japan next year :(
Well, so that's why I'm studying English :) Hope someone could can help me in my writting skills as well as my comprehension skills. Thanks
