  Most people who fail the EPA 608 didn't skip studying. They studied in a way that didn't prepare them for how the exam is actually graded, or for which questions actually show up. Here are seven common mistakes, and what to do instead. 1. Memorizing a practice test instead of learning the material Take the same free practice test five times and you'll eventually score 100%. But by then you're recognizing answers, not understanding them. The real exam draws from a different question pool, and small wording changes will throw you.

In practice, that means almost every HVAC and refrigeration technician, plus appliance techs who work on sealed systems. You don't need it if your work never opens a refrigerant circuit. Examples include duct installation, sheet metal work, or thermostat work on systems you don't break int...
