<p>I got my scores today and one was a lot lower than I expected. Kids who get B-s and Cs in my IB class have the same score as me, and I've always gotten As in that class. Is it possible that IB made a mistake in grading? Is there something I can do about it?</p>
<p>I think you can pay to have them re-grade whatever subject you want. Talk to your IBC.</p>
