<p>I wouldn’t worry about it. One B is not going to kill you, especially if it was in an AP class in the middle of a rigorous courseload. I got a B in AP Calculus too but an 800 on the Math II SAT, although that … … might be because I’m lazy.</p>

If you focus on other things, chances are that colleges will focus on them as well when looking at your application. Which is not to say that you should fail things you are not interested in. But … you know.</p>
