Do I have a chance to be a Blue Devil?

<p>I am a junior currently and my weighted GPA is 5.0 and my unweighted so far is 4.0. I founded the Interact club at my school two years ago and I was the vice-president last year and this year I'm currently the president. I am a member of NHS and I am extensively involved in high ranking orchestras and quartets since I play cello. My ranking is 5 out of my entire junior class. I just took the PSAT today, and I'm pretty sure I got a 100% on the math section and the reading/writing sections were pretty easy too, so I'm sure I'll be qualifying on SAT terms. I took the SAT II in biology and I got a 730.</p>

<p>The only reason I have a doubt in getting accepted is because I am getting a B in AP physics because it's so hard! Every other grade in my entire high school life was an A. I'm taking 6 AP classes this year. If I get B's in AP Physics, will I not be able to get into Duke? </p>

<p>Thank you!!</p>
