<p>My DH is an AP Bio teacher, and he is pretty unhappy with this year’s results. In past years, he could pretty reliably predict his students’ AP scores by how well they did in his class. This year, students he would have pegged to get 5’s were getting 3’s and feeling pretty bad about it. He also had the opposite happen - students he would have guessed would get 1’s or 2’s were also getting 3’s.</p>
