Students generally scored highest on Q3, in which they modeled reading rates for a student and a teacher. And this was the best question, psychometrically, of the exam, since its points varied significantly in difficulty, enabling good measurement of student abilities across the 1-5 AP scale. The question was worth 9 points total, and students unable to answer at least 2 of those points correctly are generally receiving AP 1s and 2s, while students who could answer 8-9 of the points are typically receiving AP 5s.
The most challenging FRQ for AB students was Q1, the modeling of an invasive plant species’ spread within a fruit grove. (Who says farmers don’t need calculus?) Students earning 6-9 points on this question tended to receive AP 5s. Writing justifications for global maxima and minima is a good instructional focus for next year.
