ABOUT THE EXAM
Format:
Part 1: 40 multiple choice questions (1 point each)
Part 2: 2 problems (choose from 3) (15 points each)
1 kinetics
1 acid-base equilibria problem, choose from 2
You will be given a periodic table, AP Exam sheet of formulae and constants, the activity
series and the solubility rules with your exam
Don’t forget to bring a #2 lead pencil and a calculator to the exam. No cell phones, please!
THE GRADING PROCEDURE FOR THE PROBLEMS
The questions are from old AP Exams and the established grading criteria will be used.
Partial credit will be given in the same manner used during the year.
