Hey Thai, I'd like to tell you not to worry about your score. I have thoroughly reviewed your essay and, based upon the scoring requirements, I can safely tell you that you will get at least a 6 with this type of writing. That is because you stayed on point with your discussions and you managed to remain clear and relevant with your 2 points for discussion. However, there are some points that you need to consider improving upon in order to improve your scoring potential.
The first thing that you have to consider is that when you deal with a direct question essay, of which this particular exercise is one, you should make sure to indicate not only your position regarding the topic, but also the main discussion points you will be presenting. That is because the opening paragraph, which requires at least 2 sentences to represent the prompt paraphrase, you also need to add the discussion outline by indicating your position and the discussion points towards the end of the paragraph. This helps inform the reader as to what the flow of the discussion will be and how it will be presented.
The next thing you have to remember is that redundancies need to be avoided in your presentation. While I understand your desire to increase your LR score, repeating information in the essay will not be helpful because it shows a lack of control with regards to word usage and grammar development. For example, when you said:
In my perspective point of view
The term "perspective" already means point of view. It is a synonym word so when you said "perspective point of view" you created a redundancy in the presentation.
Your body of paragraphs are acceptable and does make valid points. However, you presented too many points in one paragraph which did not allow you to really fully explain the purpose of the paragraph. It would be better if you pick only up to 3 strongest discussion points to present in individual paragraphs so that you can clearly explain your meaning. It is not enough to list discussion points with single sentence explanations. You need to fully explain using a topic sentence, reasoning, and clear example. All of those 3 points need to be interrelated in the paragraph with the final sentence being an introduction to the upcoming discussion topic in the next paragraph.
Overall, you did acceptable work in this essay. It shows that you have the potential to score even greater in the actual test. You just need to practice writing in the various forms to make sure that you will get at least a 6 in all the test question formats.
