This document is intended to be used throughout the course for students to journal about how they should approach and solve certain problem types. The idea is to make brief notes about the primary types of problems solved in AP Precalculus to provide a resource to use as a study tool, both for Unit Assessments and the AP Exam. This file is currently filled in almost completely by me (basically an answer key), but the info in the right column can easily be deleted in your copy to hand out to students and have them fill it in using their own words.
