AP Calculus AB free-response: students generally scored highest on FRQ1 (modeling rates) and found FRQ4 (modeling with separable diff) the most challenging: https://t.co/JBwx8UW0VT

[Trevor Packer @AP_Trevor]

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.”

The 2019 AP Calculus AB scores: 5: 18.9%; 4: 18.8%; 3: 20.6%; 2: 23.4%; 1: 18.3%.

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.

[Trevor Packer @AP_Trevor]

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+.

[Trevor Packer @AP_Trevor]

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. https://t.co/XqytdZ6xJZ

[Trevor Packer @AP_Trevor]

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.

AP Statistics Q6 (statistical inference) is the most difficult on the test, designed to identify A and B students in college; students who can answer part a are often receiving a 4; students who can answer more than part a are often receiving a 5.

[Trevor Packer @AP_Trevor]

AP Statistics Q3 (probability & simulation) can be used to predict your score: it’s a tough 3-part question, so generally: students who can answer 1 part are earning a 3, students answering 2 parts are earning a 4, and students answering all parts correctly are earning a 5.

AP Statistics free-response questions: students generally scored best on Q2 (sampling & experimentation): https://t.co/LHUkFiv1iA

[Trevor Packer @AP_Trevor]

AP Statistics multiple-choice: as is always the case, students scored much higher on questions about sampling & experimentation than about probability & simulation and statistical inference; to increase 3s,4s,5s, the free, new resources will provide help with these topics.

[Trevor Packer @AP_Trevor]

10 students so far this year, out of ~225,000 worldwide, achieved all 100/100 points possible on this year’s AP Statistics exam. (Last year: 1 student got a perfect score.)

The official 2019 AP Statistics Exam score distribution! #apstats #mtbos

[GPS Math Dept. @GPSmath]

@tackulator @TheStatsMedic Yes. Some had to go through our school's web filter. Once they entered their information, they were good to go.

[GPS Math Dept. @GPSmath]

Thank you @TheStatsMedic for this amazing opportunity to use your review program!! My students love it!! We appreciate you!!!

[GPS Math Dept. @GPSmath]

@abel_jennifer One of my two classes did find a significant difference. Such a great activity.

[GPS Math Dept. @GPSmath]

Does gummy bear brand matter? Is the distribution of gummy bear color the same for Albanese gummy bears and Meijer gummy bears?? #apstats #chisquare

[GPS Math Dept. @GPSmath]

Is the color distribution of m&ms from the New Jersey factory as claimed? Thank you @TheStatsMedic ! #apstats

[GPS Math Dept. @GPSmath]

Is there a difference in the # of chocolate chips in name brand vs. store brand? Come to AP Stats to find out!
