How this compares to the real Core exam
The real Core section is 25 multiple-choice questions, and you need 70%, 18 right, to pass it. It's closed book and proctored by an EPA-approved certifying organization. Type I, Type II and Type III are 25 questions each, graded the same way, and passing all four sections earns a Universal card.
These 10 questions cover the topics Core keeps coming back to: the three Rs, ozone depletion, cylinder safety and the new A2L refrigerants. If any of them caught you, the Core exam study guide walks through each topic, and Type I vs Type II vs Type III explains which certification your work needs. Want more practice?
