A few days after each AP Calculus BC exam, the College Board releases the free response questions from the exam. They don’t release their very succinct answer keys for a few more weeks… so… I had my students make their own answer keys as well as screen recordings of their solutions!
Official 2018 answer keys will eventually go online right here, along with the ones from past years that have already been posted.
Here are the answer keys and videos that my students created:
- 2018 #1: Answer Key, Video 1, Video 2
- 2018 #2: Answer Key, Video 1, Video 2
- 2018 #3: Answer Key, Video 1, Video 2
- 2018 #4: Answer Key, Video 1, Video 2
- 2018 #5: Answer Key, Video 1, Video 2
- 2018 #6: Answer Key, Video 1, Video 2
You can check out this project from past years here (2017) and here (2016).
Many more Williston student screencasts can be found online right here.

I disagree with a few of your answers. I believe 1c should be 414.286 hrs, 1b should be 1675 (says round to nearest whole number), 2d should be 757.456 m, 3b should be 19, and 6c should be 2^5/(3^4*4) (use the 5th degree term, NOT the 5th term). Forgive me if I’m wrong too! 🙂
Thanks for checking things over! I think you’re right!
