Look at as many sample questions as you can. Practice underlining the key points and brainstorming the topics, making plans for each one. Gradually reduce the time you allow yourself to do this, so you can do it in less than 5 minutes. See all the practice books and websites for sample questions. Lots of them have sample answers as well.
Look at the language used for making paragraphs and sentences cohesive (linking your ideas within and between sentences and paragraphs). For example: logical links that show addition (as well as, in addition) or contrast (whereas, on the other hand).
Look at the language used for expressing views. For example: ‘I believe that….’ ‘I would argue that….’, for making contrasts and concessions. For example: ‘Despite the fact that….’.
Look at the language for refuting an argument. For example: ‘There is little evidence to support the….’, for giving arguments, for providing support to your main points. For example: ‘In my experiences…’, ‘A good example of this is ….’. And in conclusions. For example: ‘In conclusion…’ or ‘On balance…’.
Think about the topics that could be used for this task. For example:
- Technology
- Crime
- Tourism
- Transport
- Education
- Population
- Media
- Health
- Society.
Brainstorm the topics for possible questions. Write as many timed essay as possible. Do the ones that have sample and model answers in the exercise books.
Before the exam, practice writing answers to the tasks in the time allowed, especially if you haven’t written at speed by hand for a while; keep up to date with current affairs.
During the exam, you should use a pen. It should be easier to write faster with a pen. Make sure you have a checklist in mind for editing your writing at the end. Make one up now with the errors you know you make.
