Writing Tips
1. Make sure you organise your writing before you begin. Use the back of your answer sheet to create a concept map.
2. The examiners judge your writing on its clarity. Make sure you have supported your ideas with specific details.
3. You can write more than 150 words for task 1 or more than 250 words for task 2, but you can't write less. You will lose points of you have less than the assigned number of weird in your essay.
4. In the introductory paragraph, paraphrase your idea. Do not use the exact words in the introduction that you use in the body of the essay. This gives your writing more variety.
5. Organise your time carefully. Leave time for planning, writing and revising.I hope you find it worthy, and these guides will help to improve writing.
