I think an answer is wrong

Tell us the citation shown under the answer — 40 CFR §82.156 or Appendix D to Subpart F, 40 CFR Part 82. That points straight at the source we used, and lets us check it in minutes.

This matters more than usual here: every question in the app stores a fragment of the regulation that proves its answer, and a question whose fragment is no longer found in the current text of the rule does not ship. If ours disagrees with the source, ours is wrong and we will fix it.

Is this the real EPA test?

No. The certification test is given by EPA-approved certifying programs, and the bank of questions they draw from is released only to those programs, under 40 CFR §82.161(c). This app does not have that bank and does not reproduce it. It teaches the federal rules those programs examine, with the section cited on every answer.

We are not affiliated with the U.S. Environmental Protection Agency or with any certifying program.

Why does the Type III exam have fewer than 50 questions?

Appendix D to Subpart F says each test draws 25 questions from the core group and 25 from each technical group. Our core group and the Type I and Type II groups are past 25; the Type III group is still being filled out. The app shows the real length of the exam it just built rather than pretending it is 50, and the group grows with each update.

Which certification should I study for?

Type I is small appliances — sealed systems with five pounds or less. Type II is medium-, high- and very high-pressure appliances. Type III is low-pressure appliances, the chillers. Universal is all three. Pick one in the app and both the study deck and the practice exam follow it.

Why does it cost anything, when the regulation is public?

The regulation is public; reading a hundred thousand words of it is not the same as studying. Each question was written by hand against the exact wording of its section, and checked against it automatically on every build.

How do I get a refund?

Refunds for paid apps are handled by Google Play, not by us. Open the Play Store, go to your order history, and ask for a refund there.
