let me attempt to comment on your essay. I didn't find any grammatical error on your essay, while you should fix your content.
In my opinion, first step that you have to do is conducting research in Virginia Tech by visiting its website. You can see more specific program that you really expect. After that, just make it relate to your interest and then explain how essential this program for your goal.
for example this sentence :
One of the most important reasons is that Virginia Tech will provide me a pathway to success.
it will better if you elaborate briefly the reason why Virginia Tech becomes your pathway. Even, words : pathway to success is too absurd, unspecific, there are a lot of schools/universities that can encourage people to success.
I hope it will help. :)
