As we did last year, we have catalogued a bunch of tweets from Trevor Packer, the College Board*® *Head of AP*®*. These are really important tidbits of information for students taking an AP class in 2017/2018, who should consider where students from the previous year tended to have trouble. Here is what Mr. Packer had to say, with tweets organized by course; scroll down to look for your course. Students should look for the AP course they plan to take in Fall 2017, and take his remarks from this year under advisement! Please also compare with our blog from last year, Some info about 2016 AP^{®} Test results

First, note these general remarks:

**Trevor Packer** @AP_Trevor June 12 When I report perfect scores, note that other perfect scores may emerge as late exams are scored, so the numbers are not final.

**Trevor Packer** @AP_Trevor June 13 2016 (ed note – this is from previous year, but still applicable). As a reminder, AP Exams aren’t graded on a curve. So when more students demonstrate mastery, the percentage of 3s,4s,5s increases.

**Students can check colleges’ and universities’ AP credit policies here, but should always confirm with the schools: Link Here**

** Trevor Packer@AP_Trevor **June 19 (1/2) For all AP exams, profs + psychometricians shift points needed up /down depending on difficulty of questions. (wikipedia: equating)

** Trevor Packer@AP_Trevor **June 19 (2/2) Thus any variations in exam difficulty=removed, so AP scores changes each yr reflect changes in student ability, not changes in rigor.

**AP Calculus BC **

**Trevor Packer** @**AP_Trevor** June 15 I’m at the AP Calculus Standard Setting today, where professors take the AP Calc exams themselves to determine scores needed for 1,2,3,4,5.

**Trevor Packer** @**AP_Trevor** June 15 One professor just said, “This is one of the best calculus exams I have ever seen; students who do well on it will succeed at my college.”

**Trevor Packer**@

**AP_Trevor**June 27 (1/2) AP Statistics multiple-choice: students knew exploring data & sampling/experimentation well . . .

**Trevor Packer**@

**AP_Trevor**June 27 (2/2) AP Statistics multiple-choice: . . . but struggled w/probability/simulation & statistical inference.

**Trevor Packer**@

**Trevor Packer**@

**AP_Trevor**June 27 AP Statistic students generally did a solid job constructing a confidence interval in Q2, the highest-scoring FRQ: Link Here

**AP Computer Science Principles****Trevor Packer**@

**AP_Trevor**June 27 (1/5) To determine the scores needed to earn 2, 3, 4, 5 on the first-ever AP Computer Science Principles exam . . .

**Trevor Packer**@

**AP_Trevor**June 27 (2/5) professors from diverse colleges took the exam themselves, evaluating each question for difficulty, using standard setting protocols.

**Trevor Packer**@

**AP_Trevor**June 27 (3/5) The professors were surprised and impressed by the difficulty of the exam, attesting it would challenge their own college students.

**Trevor Packer**@**AP_Trevor** June 27 (4/5) They established the required scores purely based on high expectations, not knowing how many students would meet those standards.

**Trevor Packer**@**AP_Trevor** June 27 (5/5) The result: kudos to the first pioneering cohort of AP CSP teachers & students, many of whom met the high standards the panel set.

**Trevor Packer**@**AP_Trevor** June 27 The (inaugural) 2017 AP Computer Science Principles scores: 5: 14%; 4: 21.6%; 3: 39%; 2: 18.5%; 1: 6.9%.

**Trevor Packer**@**AP_Trevor** June 27 AP CSP multiple-choice: students scored exceptionally well, and generally aced the questions on global impacts & analyzing impacts.

**Trevor Packer**@**AP_Trevor** June 27 The lowest scoring AP CSP questions (but still solid): interpreting data abstraction & evaluating algorithms, essential for a 3 or higher.

**Trevor Packer**@**AP_Trevor** June 27 AP CSP students generally performed well on the Explore task & the Create task; I’ll highlight the most challenging aspects of each.

**Trevor Packer**@**AP_Trevor** June 27 The most challenging aspect of the Explore task for AP CSP students = analyzing data & info; only 12% of students earned both those points.

**Trevor Packer**@**AP_Trevor** June 27 The most challenging aspects of the AP CSP Create task = applying abstractions (24% earned all 3 pts) & algorithms (35% earned all 3 pts).
