If you look at each school:
U Penn - 71% submit and I’m guessing but maybe wrong that STEM runs higher. The 25th for English is at 730 with 93% at least a 700 in English - so to me, while the 800 is great, it’s tough. I’d leave toward not submitting but only you can decide.
USC - 50% submit. The overall is between 25th and 50th but the English again is low with 82% having at least a 700 English. But only 50% submitted - to me, I would here but again it’s not a slam dunk.
BU 35% submit - and while English is above the 25th but below the 50th and the composite is above the 50th so seems a no brainer.
NEU - 45% - same as BU - makes sense to submit.
CMU - 70% submit. The composite is “just” below the 25th percentile. But 92%+ had a 700 English.
I would say BU and NEU make sense to submit.
USC is a tougher call. I would submit but statistically, and I’m looking at the overall university, with 82% a 700 English, it might not make sense. I agree with other posters that this is a STEM degree and I wish we could see STEM only English scores.
Penn and CMU - it’s one of those, if you are proud, submit. I think a lot of kids have this dilemma. My daughter was proud of her 32 ACT and wanted to submit it to Emory, W&M, etc. and was waitlisted at both. Would the decision have been different TO? No idea - but in the end, I asked her if she wanted to and she said yes because she was proud of them. At W&L, same dilemma and she got in. Rice was the one school she didn’t submit and she didn’t get in.
So you have to decide- but statistically, I would lean against CMU and Penn because very few get in with less than a 700 in English…but not none.
So no one can truly guide you - but I’d definitely yes to BU and NEU, likely submit but it’s risky to USC and I would not to Penn and CMU - but here’s the thing - you might be rejected to both regardless of submission or not.
You’ll never know the right answer unless you do what you do and get in.- so make your best call.
Best of luck.
