How to use free RBT mock exam #3

Use Mock #3 after another free set when you want a different collection of 85 questions. Work through the scenarios, then examine the reasoning behind answers you missed or guessed. The sets are not calibrated to the same difficulty, so their percentages are not interchangeable readiness scores.

  1. Choose timed or untimed. Start free without an account, email or payment card.
  2. Answer, navigate and flag. Use Previous, Next or the question navigator. Answers save on this browser; a running timer does not pause when you leave.
  3. Finish for the answer review. Unanswered questions count as incorrect. Read the correct answer and explanation for each missed or uncertain item.

What your practice score does—and does not—tell you

Every question in Mock #3 counts toward its practice percentage. This is independent study material, not an official BACB examination or a validated prediction of passing.

The BACB third-edition Test Content Outline specifies 75 scored questions plus 10 unscored pilot questions. The official exam is 85 questions in 90 minutes. Our practice questions are not actual BACB exam items, and all 85 count here; there is no hidden pilot allocation.

Turn a missed question into focused topic practice

Use the subject of a missed question to choose a guide and a focused quiz below. These are study links, not a claim that Mock #3 follows the official domain weights.

What to do after finishing

  1. Choose one recurring mistake. Include answers you guessed correctly, not only the red marks.
  2. Study the rule, then apply it. Open the relevant guide and focused quiz. Use free SAFMEDS recall cards for terms you cannot yet explain.
  3. Try a different set. Retaking the same items tests familiarity too. Check whether you can explain the decision in a new scenario.

Frequently asked questions

Is RBT mock exam #3 free, including the answers?

Yes. All 85 questions, the score and answer explanations are free without an account, email or payment card. The Premium Prep Pass is optional.

How is Mock #3 different from the main free RBT practice exam?

Mock #3 uses a different 85-question set. Use it for another attempt after reviewing a previous test. The sets are not difficulty-calibrated, so a change in percentage alone is not proof of improved readiness.

Does this mock use the official RBT passing score?

No. All 85 practice questions count here. The percentage is not a BACB scaled score, an official passing threshold or a reliable prediction of exam readiness.

When can I see the explanations?

Finish the attempt, then select a question in Question Review or choose Review All Questions. Correct answers and explanations are available without upgrading. Skipped questions count as incorrect.

Can I leave and resume this practice exam?
