AP Score Distributions
1 热门考试科目成绩分布及官方评论
Trevor's Comments:While the exam was challenging for many, AP Physics 1 scores improved over last year: an increase of 2.3% in scores of 3+ in North America.
The AP Physics data don't yet include international students, which typically boost AP Physics scores of 3+ by another % point or two.
Multiple-choice questions on Science Practice 5 (Data Analysis & Evaluation) posed the greatest challenge to students.
FRQ1 (rotation/forces) & Q5 (waves) scored lowest; half of students earned no more than 1 of 7 pts: spr.ly/6019Btp5B
1 student, out of ~150,000 scored so far, earned a perfect score of 80/80 pts on this year’s exam. No student had yet done so.
Trevor's Comments:Usually, we don’t see so much score improvement from year to year; trend continues w/Physics C:E&M: a significant boost in %5s over 2015.
Scores were highest on this FRQ2 (circuits): spr.ly/6016Btb8j
Students struggled with FRQ3 (magnetostatics), with 60% earning 3 or fewer pts (out of 15) on it.
1 student, out of 27,000, earned all 90/90 points possible on this year’s AP Physics C: Electricity & Magnetism exam.
Trevor's Comments:These don’t yet include the scores from outside North America.
Congrats to AP Calculus BC teachers & students: the strongest performance in years, so a significant growth in the % of students earning 5s.
Lowest mean score on AP Calc BC: Q6 (Taylor series); many also found Q2 (parametric particle motion) tough: spr.ly/6014Bt6zu
2 students, out of 125,000, earned perfect scores of 108/108 points possible on this year’s AP Calculus BC Exam.
Trevor's Comments:These don't yet include the scores from outside North America.
The AP Calculus AB data are in: students demonstrated stronger skills this year than last, achieving a higher % of 3s, 4s, & especially 5s.
Among the AP Calc AB free-response questions, the highest mean score was on Q4 (slope field):spr.ly/6017BshFx
Many students struggled with Q2, 3, & esp 5 (modeling volume / related rates), w/31% earning 0 pts on it: spr.ly/6014Bsh2i
11 students, out of 310,000, earned perfect scores of 108/108 points on this year’s exam.
Trevor's Comments:Students have shown slightly stronger mastery of AP Chemistry this year than last year’s group did, increasing the % of 5s in particular.
Students generally scored best on Big Ideas 1&2, lowest on Big Idea 3 (transformation).
In the Free-Response section, AP Chemistry students performed best on Q5 (kinetics / gas laws: butadiene).
FRQ6 on equilibrium/stoichiometry (EDTA) stumped the majority of students; 73% earned 0 points on it: spr.ly/6016Btung
Trevor's Comments:Scores are generally lower this year than last, but still higher than 5 yrs ago when 50% fewer participated.
Students did quite well across multiple-choice questions; the most challenging were on firm behavior and market structure.
Scores were generally highest on FRQ2 (consumer choice) & lowest on FRQ3 (monopolistic competition): spr.ly/6018BstTM
47 students worldwide (out of 83,000) earned all 90 points possible on this year’s exam.
Trevor's Comments:Once again, AP Computer Sci = the fastest growing of all AP courses this yr; great to see more schools providing this critical opportunity.
Students did quite well across all topics in the multiple-choice questions, esp. logic/software eng/recursion.
In order to get a 3+, students need to earn pts on the FRQs; students getting 1s/2s can’t do much w/these: secure-media.collegeboard.org/digitalService…
5 students, out of ~50,000, earned perfect scores of 80/80 points possible, on this year’s AP Computer Science A Exam.
Trevor's Comments:Nice work: students taking AP Statistics this year demonstrated stronger mastery overall, so there’s a solid increase in the % earning 3+.
The questions on probability/simulation were the most challenging for many students. Most students got <5 of 10 right.
Similarly, the AP Statistics FRQ4 (probability/simulation) was most difficult, w/ ~half of students earning 0/4 pts: spr.ly/6019BQEx5
The AP Statistics free-response questions’ mean/max scores: Q1: 43%, Q2: 31%; Q3: 39%; Q4: 25%; Q5: 32%; Q6: 40%.
1 student, out of ~200,000, has earned a perfect score of 100/100 points possible on this year’s AP Statistics exam.
Trevor's Comments:Interesting pattern in AP Physics C: Mechanics this year: a shift in student performance to many more 5s, a few more 2s, & fewer 3s, 4s, 1s.
Students generally did very well on FRQ1 (Newton’s laws; kinematics), > than a fourth of them earning most of the pts.
Many AP Physics C Mech students struggled w/FRQ3 (rotation; energy; Newton’s laws), a third of them earning no more than 1 point.
1 student, out of 53,000, earned a perfect score of 90/90 pts on this year’s AP Physics C: Mechanics exam.
Trevor's Comments:Good predictor of whether you scored high on this year’s AP Bio exam is how well you did on Q4 (gene expression):spr.ly/6011BQea5
AP Biology multiple-choice: students scored very well on Big Idea 2 (cellular processes), and least well on Science Prac 2 (using math).
AP Biology grid-ins that require mathematical calculation: students performed quite poorly: more than 50% earned 0 or 1 pt out of 5.
AP Biology free-response: best performance was on Q1 (allele frequencies), followed by Q5 (obligate mutualism).
Ppoor performance on Q7 (chromosomal inheritance; ~66% earned 0 pts) & Q8 (effect of exercise; ~50% earned 0 pts).
Trevor's Comments:AP US History students/teachers have perhaps achieved biggest score increases of any subject so far this yr, also w/25K more students. Wow.
On this year’s APUSH DBQ question, ~6,000 students (out of 500,000) earned all 7 points possible; ~100,00 students earned 1/7 pts on it.
APUSH short answers: highest mean was Q3 (business leaders), and lowest mean was Q1 (immigration) – but similar results across all of them.
1 AP US History student, out of ~500,000, earned a perfect score of 130/130 pts; first time we have seen that achievement in many years.
Trevor's Comments:AP Psychology scores remained quite similar, even as 20,000 more students gained access worldwide, a testament to good teaching & learning.
In the multiple-choice section, AP Psychology students earned highest means on social/developmental psych, lowest on abnormal behavior.
Students fared much better on Q2 (learning/cognition) than Q1 (sensation/perception):spr.ly/6015BQ6GT
1 student, out of ~300,000 so far, has earned all 150/150 points on this year’s AP Psychology Exam. Can’t wait to find out who / where…
Trevor's Comments:AP Macroeconomics continues to see score increases: the % of 3,4,5s is higher than 5 years ago & 50% more students are participating.
Students did extremely well on multiple-choice, esp on economic growth; most challenging were the financial sector questions.
More than a third of the students aced this FRQ3 on specialization & trade, earning all 5 pts possible: secure-media.collegeboard.org//digitalServices/pdf/ap/ap16_frq_macroeconomics.pdf. More than 40% of the students found FRQ2 on loans/demand deposits extremely difficult, earning 0 pts:spr.ly/V
28 students worldwide (out of 135,000) earned all 90 points possible on this year’s AP Macroeconomics exam.
