Hi Mahdi, you have some good ideas here. Make sure to be careful about your spaces after periods and capitalizing the first word of every sentence, but not common nouns like “people” or “specialists”. These should be easy things to correct and will avoid giving the grader an excuse to lower your score. Your writing is generally understandable, but you do have some vague phrases here and there and some incorrect word choices. Overall, I would rate this a band 5.5.
