Find the EPA 608 section to study next
Twenty-five questions across all four sections, about thirty minutes. At the end you get a readiness report that names the section you are weakest in, so you spend your study time on the part that is actually costing you points.
An average hides your weakest section. The EPA 608 exam is four separate bodies of material, and a technician who works on rooftop units all day will walk into Type III cold. Averages hide that. This check does not.
25 questions · about 30 minutes · covers all four sections
Answer honestly and guess where you would guess on the day. The point is to find the sections you are weakest in, not to get a good number.
What this is, and what it is not
It is a sample of 25 questions drawn from the same 305-question bank as everything else on this site, weighted the way the real exam is weighted. It is enough to show you where the holes are.
It is not a prediction. The real certification test is 100 questions and needs 70% to pass, and no practice sample can tell you what you will score on the day. Anyone who claims otherwise is selling something.
Your answers stay in your browser. Nothing about how you scored is sent anywhere, which is why there is no sign-up and no email box between you and your result.
