Before You Begin

How to Use This Concept Check

This is concept review, not an exam-difficulty simulation. Use it to build fluency on definitions, principles, and core distinctions. When you can move through these comfortably, step up to the 100Q Comprehensive Mock — written at real-exam difficulty — to test readiness.

Format: Multiple choice, single best answer (A–D).
Benchmark: Aim for 80%+ before test day — the BACB doesn't publish a specific passing percent, so we use a study benchmark.
Feedback: Instant scoring, per-section breakdown, and a rationale on every question.
Blueprint: Items span all 9 sections of the BCBA TCO 6, weighted to match the real exam.
Study honestly: Don't peek. Use missed items to target your next study block.
