Predicting Your AP Score
The table below shows historical statistical relationships between students’ results on the multi-
ple-choice portion (Section I) of the AP chemistry exam and their overall AP score. The AP
score ranges from 1 to 5, with 3, 4, or 5 generally considered to be passing. Over the years,
around 60% of the students who take the AP chemistry exam receive a 3, 4, or 5.
After you’ve taken the multiple-choice practice exam under timed conditions, count the num-
ber of questions you got correct. From this number, subtract the number of wrong answers ×^1 ⁄4.
Do notcount items left blank as wrong. Then refer to this table to find your “probable” overall
AP score. For example, if you get 39 questions correct, based on historical statistics you have a
25% chance of receiving an overall score of 3, a 63% chance of receiving an overall score of 4,
and a 12% chance of receiving an overall score of 5. Note that your actual results may be dif-
ferent from the score this table predicts. Also, remember that the free-response section repre-
sents 55% of your AP score.
No attempt is made here to combine your specific results on the practice AP chemistry free-re-
sponse questions (Section II) with your multiple-choice results (which is beyond the scope of
this book). However, you should have your AP chemistry instructor review your essays before
you take the AP exam so that he or she can give you additional pointers.
