<p>I think so long as you are taking Calculus AB or BC during high school I would not worry about 10th grade math issues. Overall you are a very strong candidate. EC could be boiled down so that a common theme emerges. ED acceptance rate just about anywhere selective will be much higher than RD but buried in the numbers are legacy, URM and athletic admits so it is not super clear how much better an unhooked applicants chances are. As noted though, aside from some ED II deadlines, you missed the cutoff for ED, all Ivy’s are 11/1. So long as your passion shines through in your application and you have good interviews you will be admitted to one of these top schools, which one is hard to say</p>
