I agree with blossom…get comfortable with some of the relatively higher acceptance rate schools on your list (limiting those that are affordable), as it’s most likely you will be attending one of those.
From one of your other threads:
As an international high school student, I don’t think you meet the criteria to get DARPA funds as a principal investigator (one has to be employed at a US institution IIRC.) Also, as an international, you can’t be the one completing the application for DARPA funds. What is your situation? Are you part of a team seeking DARPA funding? I only know what you wrote on your threads…but if that’s what you write on your apps, I would not believe it. You don’t have to give us details here, but make sure to get it right on your apps.
As for Putnam, you never said whether you are taking college level classes right now, which you must be to compete in December. No one has any idea how you will do in that competition. If you do make the top 100, I would contact the schools where you applied early action or rolling ASAP.
