Will you be accepted by Princeton? No one knows. Their acceptance rates are so low that no one is a “definite.”
So you apply there, and cross your fingers. And you apply to a wide variety of other schools where you would also be very happy.
Don’t let that “constant fear of being declined by colleges” rule this journey. Speak to your guidance counselor, and put together a balanced list of schools that meet your requirements. Yes, a few of them will likely reject you-- that’s the nature of this game. But that’s OK.
