Apps / Examiner

Exam prep that shows its sources.

Examiner apps help you pass professional certification exams by understanding the material, not memorizing a question bank. Every answer is checked against the official source, and the app shows you the passage.

About EPA 608

How it works

  1. 1

    Take the free diagnostic.

    About 20 questions across every section of the exam. You get a score per section, so you see exactly where you're weak.

  2. 2

    Unlock the full app once.

    One purchase covers everything. No subscription, no extra packs.

  3. 3

    Study three ways.

    Practice one question at a time, quiz yourself on a set, or sit a full timed mock exam under real conditions.

  4. 4

    Know when you're ready.

    Each section shows its readiness, and it only reaches 'ready' when you've answered most of its questions correctly more than once.

What's inside

  • Practice

    Pick a section. Choose an answer, then tap Check. You can change your mind before you commit.

  • Quiz

    A short set from the sections you pick. No hints until the end, then a full review.

  • Mock exam

    The real format: same number of questions, same time limit, same pass mark.

  • Source passage

    After every answer, the exact passage it comes from, with the document name and page.

  • Every choice explained

    A short plain-English note on why each answer is right or wrong.

  • Spaced review

    Questions you miss come back soon; ones you know come back less often.

  • Bookmarks

    Flag any question and study your flagged set later.

  • Figure viewer

    Questions that use an official test figure open it full screen with pinch-to-zoom.

  • Exam vs. current rules

    Where the exam expects one answer and today's rules say another, the question tells you both.

  • Private and offline

    No account, no tracking, no internet needed. Your progress stays on your phone.

Where the questions come from

Every question is written from official, public sources: federal regulations, government handbooks and the published exam standards. Each one is tagged to the exam's official outline so coverage matches the real test, and checked so the correct answer is supported word for word by the passage it cites. A [practitioner] reviews each exam's questions before release. We don't copy questions from the real exam or from other apps.

Free diagnostic. Then one purchase of $14.99 per exam. No subscription. iPhone and Android.

Questions

Are these the real exam questions?

No. The official question banks aren't public. Our questions are original, written from the same official sources the exam is based on, and they follow the exam's official outline.

Do I need an account or internet?

No. Everything works offline and nothing leaves your phone.

What if I find a wrong answer?

Every question shows a short ID. Email it to [email protected] and we'll check it against the source and fix it in the next update.

Is this a subscription?

No. One purchase per exam app, and updates are included.

Examiner apps are independent study tools. They are not affiliated with, endorsed by, or sponsored by the FAA, the EPA, or any testing provider. Questions are original and are not taken from any official exam.
