| https://www.washingtonpost.com/news/grade-point/wp/2016/02/1... > Nearly 2.5 million students took a total of almost 4.5 million AP tests overall last year. Of the test-takers, just 322 obtained every point possible on an AP test, and perfect scores were logged on 21 of the 36 AP exams. Here’s the breakdown of those perfect scores: 67 in Computer Science A 55 in Spanish Language and Culture 54 in Microeconomics 36 in German Language and Culture 22 in Macroeconomics 16 in Studio Art: Drawing Portfolio 12 in Calculus AB 11 in Calculus BC 11 in Physics C: Mechanics 7 in Japanese Language and Culture 7 in Studio Art: 2-D Design Portfolio 4 in Chemistry 4 in Psychology 4 in Italian Language and Culture 3 in U.S. Government and Politics 2 in French Language and Culture 2 in Physics C: Electricity and Magnetism 2 in Statistics 2 in U.S. History 2 in Studio Art: 3-D Design Portfolio 1 in Latin ----- Surprisingly low numbers, considering how many hundreds of students ace their calculus tests in college. |
I'm surprised however that Chinese has no perfect scores. I remember some students that had moved from Taiwan or China would take AP Chinese to get free college credits. The grammar of Chinese is so simple compared to Latin or Japanese. And from what I recall, AP Chinese tested Mandarin at a 2nd grade level, and didn't test much or any of the chengyu (成語: Chinese proverbs) of which are difficult because of the shear number to remember.
Perhaps graders could tell they were native speakers, and thus raised the bar? (I took 3rd-year Chinese as a filler class "language requirement" in college and the professor expected high-school level of Chinese while she expected chicken scratch from others for the same grade.)
AP Computer Science seems likely to have a good number of perfect scores. I remember a test reviewer telling me that they often overlooked syntactical errors (unbalanced parentheses) and would allow API calls to incorrectly labeled API functions. (I don't disagree, because CS is more about understanding data structures than it is knowing how to put code on paper without an IDE or reference.)
