<< I am still wondering about the scoring scheme on this years AP test....
Something like this? Sec I Part A 28 Q (number correct - .25*number wrong) = part A score
Part B 17 Q (number correct - .25*number wrong) = part B score
Section II 9 points for each of the 6 problems. = 54 points
Then what? How would you compute a composite score? How would you weight the multiple choice parts? something like this:
(part A) * 25% + (part B)*25% + (free response total) *50% = your score?
No quite. The total part 1 scores (A+B together) is multiplied by 6/5 (= 54/45) so that each half is worth 54 points for a total raw score of 108. The raw score is then closely analyzed by the Chief Faculty Consultant and the statisticians at ETS to set the cut points for 5,4,3,2 and 1 so as to be sure a 4 (or 5 ,3 2 or 1) this years means the same level of achievement as a 4 (or 5 ,3 2 or 1) in past years.
