In my opinion…all this will do is guarantee that your application is read and not put aside in the first go round. You haven’t done anything personally with this higher end person. They can’t really even give you a character reference, because they don’t know you. All they can do is pass your application on to admissions for a probable review.
Consider this for what it is.
Re: your AP test scores. Except in a very few cases, you don’t have to submit these at all until after you are accepted…to possibly get course credit. If you are worried about them, don’t submit them now.
And I agree…you need a well balanced list of colleges on your application list…not just tippy top ones. Your current GPA is on the lower side for these tippy top schools…and unless YOUR family donated money for a building…the connections likely won’t make up for any deficiency in your application.
