Problem Sets

The problem sets in this course are openly licensed, and are available as-is, or can be modified to suit your students’ needs. In these problem sets, students are given an opportunity to apply the quantitative-reasoning skills they learned throughout the module.

Answer keys are available to faculty who adopt Waymaker, OHM, or Candela courses with paid support from Lumen Learning. This approach helps us protect the academic integrity of these materials by ensuring they are shared only with authorized and institution-affiliated faculty and staff.
