# UnLock Math Curriculum

Pre-Calculus is the direct successor to Algebra II. It builds on the concepts of Algebra II and prepares students for Calculus.

## Curriculum

## Pre-Calculus

Pre-Calculus plays a crucial role in preparing students for calculus and post-secondary mathematics. This course focuses on more abstract and theoretical concepts, allowing students to improve their critical thought processes. The primary goal of this course is for students to own a thorough understanding of all types of functions and prepare them for Calculus.
