<p>My D is an IB diploma holder, also. All her credits were accepted (I don’t know anywhere that HL classes with good scores aren’t accepted, even Bryn Mawr and Harvard accept them). She was able to receive credit for almost all her core requirements. Which allows here to double major and still graduate in four years. The best thing about her IB/AP credits is that it puts her at the front of the line of her class in registering for the next semester’s classes.</p>
