If your 4.0 GPA was earned in classes that are the most rigorous your high school has to offer, you will be considered a serious candidate at any school to which you choose to apply. In that case it will come down to your essay, your ECs, whether or not you have a hook or a spike, and possibly your demonstrated interest or your interview. The AOs will also think about what the college can do for you and what you might do for them. If you are a borderline candidate, the AOs will be considering all this in relation to the other candidates. So with all that in play, it is impossible to calculate the odds. You’ve got a ticket into the ballpark, though. Keep up the good work!
