Curious about this as well. What did you do your research on? It would be great fodder for essays, I would think. And couldn’t you use the same folks who wrote you recs for that for your applications? They had to be good. Also curious about what instrument you play, as that has to take up a lot of time on top of all the other stuff you’re doing.
And it’s a lot of stuff. A LOT of stuff.
I wouldn’t sweat the math grades.
