I've been lurking here for a while but wanted to share my story because I wish someone had told me this earlier. I failed the BCBA exam in September and again in January — both times I scored around 68%, just shy of the passing mark. I was devastated. I'd been studying for months using just the task list and my grad school notes, but something wasn't clicking.
What changed for me was switching how I was practicing. Instead of re-reading content, I started doing timed BACB practice test sets daily and actually analyzing why I got things wrong — not just moving on. I also found a solid study guide that broke down experimental design and behavior reduction procedures in a way my textbooks never did. Those two content areas were killing me.
Third attempt I passed with an 82%. The volume of practice questions made the real exam feel familiar rather than terrifying. If you're stuck, I'd genuinely love to share what resources I used — just ask below.
