Impressive ECs - depth and tenure matter - and leadership doesn’t mean you have a title. You can lead without being given a title, in other words.
But it’s quality, not quantity and you seem to have it.
But no one can predict, you have this, therefore you’ll get admitted.
That’s why people are suggested other, less difficult to get in schools - although you have RPI and WPI, etc.
All you can do is put your best foot forward and it seems like you’ve set up to do so.
You can’t decide for the schools - if they should admit you. You an just put the best you forward - and that has to be good enough.
If they don’t admit you - their loss.
Successful people in society come from a such a wide range of colleges - really most all of them - and many successful people don’t come from any college at all.
Don’t put so much pressure on yourself. You’ve positioned yourself extremely well - from sports to research to class rep, etc.
Be the best you and the chips will fall where they may - and you will make your success - moreso than the where you go - and with a drive like yours, that’s a good thing!!
