Is this for first-time or repeat test takers?
Both. Start with the free practice to see how UB explains concepts and question breakdowns. Then choose additional support based on the areas you want to strengthen.
Which package should I choose?
Choose Beastslayer for a course-led study plan, Super Ultimate Mock Bundle for a practice-focused bundle, or Complete Beast Mode for the course and practice tools together. Each product page has the full inclusions and access terms.
The correct question to ask yourself is "how much do I want to learn about my profession?" to make this decision.
Does a prep course guarantee a passing score?
Simple answer - no. Passing the BCBA exam depends on many factors such as university program, supervision experience, and study habits.
Our Beastslayer course typically raises student scores 25-50 points after a 30 day run (Est. 25-40 hours of studying) and has resulted in 100s of first time passing BCBAs. Results not guaranteed or promised in any way.

Nick Ostosh, MA, BCBA
Nick started Understanding Behavior to help students figure out why an answer is right. In his free live teaching sessions, he breaks down BCBA exam questions one decision at a time.
That same approach runs through the Beastslayer course and the mini mocks. Each practice question gives you a chance to spot what you missed and decide what to study next.
