During my junior year of high school, I found my passion and knew at that instant what I wanted to do in life.
This sentence is a little redundant because of the sentence that comes before it.
You have something like 12 sentences in this essay, and the only sentence that answers the prompt is the first sentence of the last paragraph... and that sentence does not even answer the prompt very well! So... even though you write very well, I want to encourage you to take out that irrelevant middle paragraph and start over with a focus on several specific goals. They want to know about your goals. There should be several.
:-)
And that is only half of it! After telling the goals, show that you chose this school because of specific qualities it has that relate to your goals.
