Other tips:
• Use a lot of action verbs! This automatically makes your writing sound mature and helps it flow with ease (i.e. “The author conveys” instead of “The author is conveying.”)
• One personal example is always good: it is probable that no one else has one just like yours, and the scorers might be impressed by your originality.
• Don’t dwell on the introduction. If you find you are having a hard time getting started, simply write out your thesis and move on to your supporting paragraphs!
• Keep an eye on your watch: the time frame is the most difficult part of the essay, so make sure to keep tabs on how much time you have left so you can conclude your essay properly.
• Breathe in, breathe out: the more stressed and worried you are, the less you will be able to concentrate and think clearly – and express yourself clearly!
