608Wise: EPA Practice Test

NOT A GOVERNMENT APP: 608Wise is independent study material from Buckshot Digital Sales Inc. It does not represent, and is not affiliated with or endorsed by, the U.S. Environmental Protection Agency (EPA), any government entity, or the ESCO Institute. It does not issue certifications; the official Section 608 exam is given by EPA-approved certifying organizations.

608Wise is EPA Section 608 exam prep built on three promises: the question bank is current (written for the AIM Act rules in force in 2026), every answer is explained in plain language with the regulation it comes from, and the pricing is honest. The complete Core section is free forever, and one purchase unlocks everything else. No subscription, no account, no ads, and it works fully offline.

400 ORIGINAL QUESTIONS
- 100 each for Core, Type I, Type II, and Type III
- Written for the current rules: AIM Act phasedown, A2L refrigerants, and the requirements in force in 2026
- Every answer explained, with a primary-source citation
- A complete Spanish version of every question and explanation, switchable in app

FREE FOREVER

Note on Google Play services: 608Wise's one-time unlock is built on Play Billing, which may send Google its own basic diagnostics as part of normal operation. 608Wise does not add any analytics, ad, or tracking SDKs of its own. See the Data safety section for details.
