Undergraduate / Cornell Arts and Sciences Supp - the ability to combine my interests in biology and research [2]

If this is for early, my feedback might be too late...
I think that rather than naming and describing each of these courses, you could focus more on creating a cohesive idea of what you would like to do with what you learn at Cornell. Like if you have a specific goal or field of study in mind, you could talk about that. Also, the A&S prompt asks specifically about why the flexibility of the curriculum is ideal for you, so you should also address that.

Good luck!

Undergraduate / Common App Essay on movie spoilers (Prompt #7) [4]

"... the most breathtaking scenes, and the most spine-tingling scenes ..." - it's repetitive to use "scenes" twice here.

I would suggest rearranging this sentence to eliminate the passive voice - something like "Trailers display the best jokes..." There are also other places where you repeat a word multiple times in the space of one or two sentences, like at the start of the third paragraph.

Content-wise, I think it's pretty good! I'm just wondering about your conclusion, though. If you refuse life advice from someone for fear of "spoilers," isn't that contradicting your message of open-mindedness?
