<p>I feel bad for you. I also had this problem (interestingly, in the same class as well). One teacher had grade deflation (although not as major as yours had) and one teacher had grade inflation. My friend, a very smart, hardworking student, got both B+ in one class and 5 on the AP, while another friend, decently smart but not all that diligent, got both A+ in the other class but only 3 on the AP test.</p>
