When I applied to the university, I had to prepare the documents correctly and write an essay without errors. I know that I have problems with the grammar in the English language, since this isn't my native language and I decided to contact the proof reading service, I found this service here https://www.essayedge.com/mba-essay-editing/
. These guys read my essay and told me how to fix the mistakes, they also shared tricks with me how to make the essay more interesting and show my best side, so that I had a little more chance of going to this university. I think that you also need to find a similar service and prepare your papers correctly. All documents must comply with the rules for the selection committee, otherwise you may not seem too motivated to study in this place.
