Help me please

Somebody help me please.. I've been joined AFS program, that is a program that holds exchange student ( go abroad ). I've been registered and did a finalization of the form, I also went to the chapter in Papandayan Semarang to ask the stamp of participant card and give my agreement statement from my parents. I chose United States for the prominent country and Australia for the other country that didn't display in the form. Actually, I really want to go to Australia because I think the country is not too far from my beloved country, Indonesia. The other reason is In Australia, use English language, the other language beside Indonesian I can little speak. There is a fear feeling in my self, because there are many participants from Semarang in this program. I estimate, there is about 500 participants from Semarang and surroundings. Now. I am trying my hardest to speak English fluently, I am writing everything use English, I am searching an information about United States and an information about world, I am trying to do a TOEFL test, and others. I imagine if I can pass the test on 29th April and pass the second and third test, I think, of course, I am really happy can go abroad. However, many the other student that speak English more fluent, can write a story in Indonesian with interesting idea, and know well about the hot news in the world. I just try, try, and try, and also pray to God. Hope God will give me a a luck through a good teacher that can teach me to help me..
