How you finish Month 4

Each week has video lessons with notes and an assignment, and then a 10-question quiz. After that, the month ends with a 20-question exam. So score 80% or higher on every quiz and exam and finish your assignments. Then your instructor reviews the month and releases your Month 4 Certificate of Completion, and the next month opens.

This course is part of the full HVAC program, and you enroll in all six months at once on the tuition page. Safety always comes first: for example, OSHA explains its hazardous energy rule at 29 CFR 1910.147, and EPA explains refrigerant rules on its Section 608 page.
