This article is strange. Unless something has changed recently, AP exams do not have a concept of pass or fail. You get a score and colleges can choose to give you college credit based on the score.<p>I got a 1 on the AP Calculus exam but colleges wanted a 3 or a 4 or a 5 depending on their requirements to give me credit for college calc. So I have no idea what it means to have everybody &#x27;pass&#x27;.<p>I have no doubt he&#x27;s probably an exceptional teacher. That AP Calculus test was really really hard when I took it a decade ago, but the metrics don&#x27;t make any sense to me
