Engg Essay question guidance please?

I have just written an essay on an incident that I faced in programming and how the incident helped me realize a little fact about the world, and how the entire incident relates to my decision to apply to princeton. However, I'm not sure if the answer explicitly answers my experiences (which I have outlined in the summers essay). What do you guys think I should do?</p>

<p>Further, if I'm applying for Computer Science A.B as my first interest and Computer Science (BSE) as my second option, do I still submit a supplemental engg essay?</p>
