@smally01, while I admire your desire to write so many English words to help increase your LR and GRA score, writing 407 words is unrealistic in a pen and paper exam room setting. Specially when you only have 40 minutes to outline, draft, review, correct, and finalize the content of your paper before submission for scoring. You should not write more than 275-300 words for this essay. Personally, I have always told my students that writing 275 words at the most allows them to have enough time to apply edits and changes to the content at the end of the drafting process. The same should apply to you. Remember the most basic rules for successfully writing a task 2 essay:
1. No more than 3 body paragraphs
2. Do not discuss more than one topic per paragraph
3. Do not write less than 3 but no more than 5 sentences per paragraph.
4. Do not present new ideas for discussion in concluding paragraph. Just summarize the essay and present a closing sentence to end the discussion.
Do not present information in the opening paraphrase that is not included in the original prompt such as
Some people raise their concern of that to bring negative impact to the society such as the increase of financial burden on tax payers. While others treat elder people's skills and experiences as a vital resource for many of startup companies
This is not a direct question essay. It is a comparison with personal opinion essay so the actual discussion of facts and reasons should only be done within the 3 body paragraphs. The opening paragraph should be used in the manner it is intended for which is the paraphrasing of the original prompt, without changing nor adding information to the discussion. The same rules apply to the mistake that you made in the concluding paragraph.
