Let’s step back from this - what are your targets and more importantly safeties ? You have no private EAs ?
Most are telling you - right or wrong - Stanford and Penn aren’t happening (my opinion) or are reaches (other people’s opinions). GPA wise, lack of language etc.
You need to develop a real list of targets/safeties - I don’t feel like you’ve given this a true review but it’s more important than your current list.
If you end up with a private with EA - ie Case or RPI which could both fit your needs and there’s no doubt more - then it would behoove you to apply EA to them and RD to Stanford to enhance your chances to them.
