Matt’s exam tip

Do the paper first, then check the scoring guidelines. The scoring guidelines are most useful after you have attempted the question properly, because they show exactly where the marks are awarded.

What About Multiple-Choice Questions?

College Board does not usually publish full AP Chemistry multiple-choice papers publicly in the same way that UK exam boards publish full past papers. Some secure practice questions are available to teachers through AP Classroom.
