For those of you applying (or who did in the past) with the Option B for a graded paper, what exactly are you submitting? Is it like an AP History DBQ essay or any research paper? Or could it be an AP English paper about a novel/quote/essay?
I think both of those would be absolutely fine; just whatever you think is better writing is what I would send. Make sure neither of them were graded poorly (obviously!). As long as it’s an A or maybe a B if it’s still very good writing, you should be good.
I personally am submitting my Extended Essay (it’s a long social studies research paper on the Syrian civil war, so it’s probably closer to a DBQ).
