Students will love these Self- checking Calculus Circuits for practice. Teachers will love these, too, as they include fully typed solutions. No Prep! Circuits are from AP Units 1 - 9*. If you have never used circuits, then the best way to describe them is a combination of a scavenger hunt and worksheet with the answers embedded. Students start at the first problem, and after solving it, search the circuit for the correct answer, completing the problem in that section. This continues until the
