6 CLEP credits, B in course, but 2 on AP Spanish exam

<p>Son is in shock over his score of 2, but thought the exam was very difficult. How can someone get 6 credits from CLEP, but fail to get any credits from the AP test? One friend, who got an A in the class, got a 3 and didn't think that would get him any credit at Ohio State. They really worked hard in that Spanish class and it was their 5th year of classes.</p>
