Very helpful and worthy!!! Contrast to other institutions, Zhishiq is much more helpful since the editors (sorry I think there should be a better term but I do not know) here are mostly native speakers and experienced at editing papers. They are helpful and responsible. Another advantage of Zhishiq is the price. The price is very nice comparing to other paper-editing institutions. Highly recommended!
Henry is very helpful in a timely manner. He replied to every draft immediately. Also, he is so responsible to every words I wrote. He is very encouraging and helped me a lot on coming up with great ideas. Highly recommended!
Thank you very much for your kind review! - very best of luck with your application!
