Hoang, I am not sure if you responded to the original prompt you were provided properly because you did not post the original prompt even though I left notice for you to do so. Therefore, you cannot expect me to deliver a complete and accurate review of your work. I can only review the obvious problems. I will not touch on how you responded to the prompt and how you could have improved your response because you did not want to tell me what the original prompt was for some reason. So you cannot expect complete help from me in this instance.
I believe that you mistakenly began the discussion of reasons for the advantages of playing sports in the opening statement. What you presented, from what I can read, is not an accurate prompt restatement because you were already doing a discussion in that section rather than simply restating the prompt topic, reasons, and discussion instructions. Please remember that the first paragraph is always the prompt restatement and, unless you are writing a direct response essay, you are not to begin the discussion in the first paragraph. The discussion follow in the 3 succeeding paragraphs instead.
You need to learn to better develop your discussion points. Don't limit yourself to 3 sentences per paragraph. Whenever possible, write 5 sentences so that you can better explain your reasoning and provide an appropriate example in the paragraph. The current set up you have displays under developed discussions and a lack of proper information to support your topic sentences.
Aim to be clear in all of your presentations. The following line is quite confusing and will result in a lowering of your GRA score:
Today, they must learn such a lot that they feel tired with huge number of exercises, so some can take great emotional stress
Are you discussing academic activities or sports activities? You lack a connecting sentence in the paragraph that could have clarified and connected the discussion in a manner that is understandable to the reader. Clarity is key in your presentation because when you are incoherent in your presentation, your C&C score could receive a failing mark.
The conclusion is too short. You need at least 3 sentences to offer a complete paragraph for scoring consideration. The conclusion you presented lacks a second prompt restatement to remind the reader of what the whole point of the discussion is about in relation to the reasoning you presented.
