## Resources for this module

Find videos, documents and calculator files (as needed) to aid in your teaching of questions found on the AP® Calculus exam.

## Videos

The videos below are divided into two sections: resource and technology. In the resource videos, you’ll find information on scoring, common misconceptions and techniques for approaching topics in the released free-response questions. The technology videos show the tech solutions available using your graphing calculator.

## Resource Videos

### These videos present the solutions, relevant AP® Calculus concepts, and typical scoring guidelines and interpretations associated with specific parts of the mock 2020 AP® Calculus exam. The detailed solutions emphasize the AP® Calculus mathematical practices and skills and include a reasonable expectation of how each would be scored.
