Need help in english

Okay. Im having my national engliah examination on 4 september 2008. I MUST pass exams because it is really very important and im serious.
However, im not good at english and I have a quite high percentage that I will fail this english exam. I got 70...

over 140 for my previous school english exam. So now I only got 50-50 to pass this national exam.
Normally I wont do well on the comprehension but, my composition will pull my up. Today is the day for me to study my english. So.. Can you guys give some topics for me to practice on and I'll give it to my teacher for marking.

By the way, thanks to you people, really. I passed my english composition because I chose the topic " describe your country". Some people in funadvice will ask me about my country.. So I know how to write about that fairly well.

You may also want to teach me some useful words like "utterly" or something. I leant these words from a person in funadvice too. And I hope I could learn more before my exams.

Hope to hear from you soon. Thank you.

well good luck for the test
your english seems quite well from what I've just read
but another good key to knowing english well is being able to know how to write the different words that sound the same

example:

right, write
their, there, they're

im a llittle sleepy now but I will try to think of more for you
good luck with the test!!
