2019 AP Calculus Scores

From @AP_Trevor on his twitter page:

This year’s AP Calculus AB students demonstrated a slightly stronger mastery than students in 2017 and 2018, so there’s a slight increase in % of exams earning scores of 3+ this year.

  • The 2019 AP Calculus AB scores: 5: 18.9%; 4: 18.8%; 3: 20.6%; 2: 23.4%; 1: 18.3%.
  • AP Calculus AB multiple-choice: students generally scored highest on questions on “applying the mean value theorem” and lowest on questions about “derivatives as functions” and “interpreting and applying integrals.”
  • AP Calculus AB free-response: students generally scored highest on FRQ1 (modeling rates) and found FRQ4 (modeling with separable diff) the most challenging

Great job, AP Calculus BC teachers and students: this year’s students achieved a significant increase in mastery: ~7,000 more students will earn 5s this year than last; at the same time, access increased by ~5,000 students.

  • The 2019 AP Calculus BC scores: 5: 43.2%; 4: 18.5%; 3: 19.8%; 2: 13.6%; 1: 4.9%.
  • 7 students so far this year, out of ~145,000 worldwide, earned all 108/108 points possible on this year’s AP Calculus BC exam.
  • AP Calculus BC multiple-choice: students triumphed over questions on “interpretations and applications of derivates” (EU 2.3); the lowest performance was on questions focused on “derivatives as functions” (EU 2.2.).
  • AP Calculus BC students scored very well on FRQ1 (modeling of rates); to score a 5, AP students are typically earning 6/9 points on this question to equal the performance of college calculus students who receive As in the corresponding course.
  • The most difficult question on this year’s AP Calculus BC exam? FRQ2: polar-area. ~20% of students scored 0/9 on it. Because it was also difficult for college calculus students, AP students only need to earn 1-2 pnts on it in order to equal the college students and thus score 3+.
