I first got a bunch of comments from my professor after I sent her the first draft which the writer revisited really fast and I didnt have to pay any extra.
The points covered in the essay were very strong and understandable.
Although I had to extend my deadline twice for the expert to complete the work, they still eventually did the work and did a very good job.
However, things got better when I approached them and told them that I want avail book writing services.
A great course, good lectures and good tasks to help you get started.
