Knowing that you'll pass, before you pass.

Practice questions help you identify testable content, recognise patterns, and train your brain to apply behavior-analytic principles quickly and accurately—skills critical for succeeding under timed, exam-like conditions. High quality practice questions also mimic the questions you’ll get in the actual exam.

Tracking your revision analytically reveals strengths and weaknesses early, ensures efficient time allocation, and allows targeted improvement in areas most likely to influence your final score.

All-in-one revision tools, like Kinnu BCBA, provide convenient access to streamlined notes, practice questions, and real-time progress tracking, making your revision structured, efficient, and effective.

The BACB publishes annual pass rates: first-time test takers typically pass at around 60–65%, while retake pass rates are far lower. Pass rates vary widely by verified course sequence provider. Additional high-quality questions are always valuable and in short supply which is why we built Kinnu.

Candidates consistently find Experimental Design, Measurement & Data Display, and Concepts & Principles the most difficult content areas—these require targeted revision due to historically lower candidate scores.

Effective strategies include setting checkpoints (e.g., 45 questions per hour across the 4-hour, 185-question exam), flagging difficult questions for review, quickly eliminating wrong options, and pacing yourself to avoid spending too long on individual questions.

Candidates who complete multiple full-length BCBA mock exams and several thousand practice questions achieve significantly higher pass rates than those who rely on reading alone. That’s why the Kinnu MCQ question bank is constantly increasing!

You should start practising questions at the very beginning of your revision, ideally at least 3–6 months before your BCBA exam date. Early practice helps identify knowledge gaps, builds exam familiarity, and improves long-term retention.

AI-powered study tools, like Kinnu’s LARA, can help you save time by quickly providing instant explanations for complex behavior-analytic concepts—maximising efficiency and retention.

Key statistics to track include your overall MCQ correctness score, scores by individual BCBA content area (highlighting weaker areas), timing per question, progress in mock exam scores, and frequency of repeated mistakes. Monitoring these metrics ensures targeted revision, efficient use of time, and measurable improvement.

Kinnu’s practice questions are ‘good’ because their length and difficulty is consistent with those candidates are likely to see on the actual exam. This is achieved through a hybrid AI + human expert drafting process whereby a bespoke AI model (trained on the BACB Test Content Outline, the Ethics Code for Behavior Analysts, and core ABA texts, coupled with top students’ notes) produces questions which then go through multiple layers of human review by recent exam passers, top tutors and BCBA-D experts. They are also constantly revised to keep up to date with the Test Content Outline.
