Classfinder Pro is a free extension to the Western Washington University's Classfinder web page.

Classfinder Pro allows you to find information about the course such as the number of credits, prerequisite courses, and the building where the course is located.

This allows you to make an informed decision about whether you should take the course and will help you find the necessary prerequisite courses you need to pass.

Classfinder Pro allows you to keep up with what you have already taken and to search for the courses you have yet to take.
