Please It is really important to me…
This is for my admission document to apply Ph. D program. I hope you are familiar with this major (hospitality or marketing).
When I count words, it was 606words but please make it a bit shortly by using changing grammar, expression and story.
I am not sure will you check the contents also?
Anyway I hope you to check everything including words, grammar, and expression. I hope it will be ready to go.
