How Section I and Section II Become an AP Score

The exam has two sections that get combined into one composite score, but they are not combined evenly. Section I, the multiple-choice questions, is worth 45 percent of the total. Section II, the three essays, is worth 55 percent. That 10-point gap matters more than it looks, because Section I spreads its 45 percent across 45 separate questions, while Section II spreads its 55 percent across only three essays. Each question is therefore a tiny sliver of the score, while each essay is close to a third of a much bigger slice.

Do the division and the gap gets concrete. Forty-five questions sharing 45 percent means each question is worth roughly one percent of the exam. Three essays sharing 55 percent means each essay is worth roughly eighteen percent. So one essay is worth about as much as eighteen multiple-choice questions. That is why a single rubric point, each essay scored 0 to 6 on thesis, evidence and commentary, and sophistication, can shift the composite more than several extra correct answers.

This weighting is the reason essay practice pays off more than drilling extra questions once you are already doing reasonably well on Section I. A student answering 33 of 45 correctly has a solid but not perfect Section I. If that same student is scoring 4 out of 6 on all three essays, raising each essay by even one point does more for the composite than picking up several more correct answers, because that point is multiplied across a third of the larger section rather than a fraction of the smaller one.
