How this practice test is set up

The live EPA 608 exam is 25 multiple-choice questions per section, 18 correct (72%) to pass each one. CertReady’s bank covers the same topics with original questions — ozone and the venting rule in Core, 80/90% recovery in Type I, leak rates and evacuation levels in Type II, vacuum operation and 25 mm Hg in Type III.

Start with a 10-question mixed set if you have ten minutes. Switch to one type when a mock shows a weak section. Sit the timed mock when you can hit 80%+ on each category; passing is 72%, and you want margin.
