How to send us a problem set
CPM problems are numbered consistently, which makes this quick. The more precisely you identify the set, the faster the turnaround.
- The course name and number, for example Core Connections Algebra
- The chapter, lesson and problem numbers, such as 7.2.3 problems 45 to 52
- A photo or scan of the page if the numbering does not match your edition
- Any work you have already attempted, so we can show where it went wrong
- Whether your teacher requires a specific method or representation
- Your deadline, since most sets can be returned the same day
