Erica Arrington, a calculus teacher in Massachusetts, was inspired to write a higher level circuit and wants to share this with other teachers for free! It has the same format as the other circuits where students do the first problem and then search for the answer and then that becomes the next circuit.
This is a 12-question circuit.

Hopefully she will write and post more advanced circuits!
