Your attempt saves on this browser; a timed attempt keeps counting down while you are away. Independent practice, not actual BACB examination questions.
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.
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.
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.
Choose a measurement method, calculate rate and read a graph.

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