1. do past year questions, to get use to the question's logic and direction.

2. read newspaper or magazine to study how others elaborate their points, and steal some words that you think might be useful in writing essay.

3. practise english conversations, or even have a small debate to discuss something among your other classmates, purpose is to point out grammatical mistake or pronunciation problem with each other and get use to talk in english.
