If you're looking for EVEN MORE ADDITIONAL practice, here are a couple of old exams that we recommend:
- 2012 Practice Exam (MC *and* FR)
MC begins on page 23 (key on page 86),
FR begins on page 69 (scoring guides begin on page 88)
- 2018 Free Response Exam (FR only) and scoring guide
And you can find many more old FR exams on College Board's AP Statistics exam info page.
