So the prompt is this:
Engineers turn ideas (technical, scientific, mathematical) into reality. Tell us about an engineering idea you have or your interest in engineering. Explain how Cornell Engineering can help you further explore this idea or interest
I then went on this blog
Cornell Engineering Admissions: I only need to write one essay, right? and found out that the essay was supposed to be an idea.
I am freaking out right now because I wrote my entire essay on my interest in engineering and how Cornell Engineering would be good for me.
Is my essay totally off topic or did I interpret the question correctly?
