The connection may help with admission but you can’t count on it. Are you applying SCEA or ED? You don’t have to tell us but I would strongly recommend that in this situation. Also run the school’s net price calculator to make sure it will be affordable (unless you are full pay.)
I agree with dadofjerseygirl that your uw GPA is on the low end for these schools…does that gpa only include core courses? As for AP test scores I would only report 4s and 5s on your app.
Make sure to have a college list that includes a few reaches, a handful of targets and at least one affordable safety/highly likely school. Try to find a school with rolling admissions so you have at least one acceptance in hand before this Ivy releases decisions. If you want help developing a list let us know. Good luck.
