MCCE Study Guide for Praxis CS 5652 Exam

 

 

The five content areas tested on the Praxis are listed below (Roman Numerals I-V)

The lessons are from the AP CSP Review and Computer Science resources, developed by Khan Academy, which are licensed under a CC-NC-BY-SA-2.0 license. The alignment of Khan units and lessons to the ETS CS 5652 Praxis content outline was done by MCCE.

These are the areas that are covered using the Khan Academy materials. 

NOTE: If you are in one of the MCCE Study cohorts, please request a join code from your instructor to get credit for completing lessons to fulfill the study program requirements.
