BCBA exam — how do people keep early material fresh while pushing into new task list areas?

Single-subject design questions clicked for me when I stopped memorizing definitions and started drawing out what each design looks like graphically. Once I could visualize the phase changes and data patterns, distinguishing between them got a lot easier. That shift took about a week but my scores on those questions went from around 55% to 80%.

At 12 weeks out and averaging 65%, you're in a reasonable place. The last 4–6 weeks of prep usually see the biggest score jumps because everything starts connecting. Keep the consistent hours and don't burn yourself out with an unsustainable schedule now.

The ethics section is more specific than most people anticipate. The BACB guidelines around supervisor-to-supervisee ratios, documentation timelines, and dual relationship rules are all testable details. I'd block at least a full week just for ethics before your exam date.

The 30-minute daily review approach worked really well for me. I used spaced repetition flashcards for the vocabulary-heavy content and saved longer review sessions for experimental design and measurement, which require working through scenarios rather than just recall.

Honestly, I felt this exact way around week 10. I'm a full-time BCBA-D supervisor so I was squeezing study sessions into lunch breaks and after the kids went to bed, which made retention even worse. What actually helped me was doing a quick 10-question mini-quiz on older domains every single morning before I touched anything new. Like, before I even opened my notes on a new task list area, I'd drill myself on something from three weeks ago. It kept old material alive without eating into my actual study time.

The other thing I'd say is don't try to re-read old notes when you're tired. That's just wasted time. Flashcard-style active recall right before bed or during a commute is way more efficient, even if it's only 15 minutes. It felt slow at first but my practice scores on the early domains stopped dropping once I built that habit. You're closer than it feels right now.

I failed my first attempt partly because of exactly this problem. I was so focused on getting through new content that I let everything from the first few weeks just evaporate. What changed the second time was I stopped treating review as optional. I built in one full "no new content" day each week where I only did old flashcards and practice questions from the earliest task list sections. It felt wasteful at first but my retention on those foundational concepts was way better by exam day.

Also, don't underestimate spaced repetition for the stuff you covered 8 weeks ago. I wasn't using Anki the first time and it made a massive difference the second time around. Even 20 minutes a day on old cards kept things alive in a way that rereading my notes never did. The task list is a lot, but it's finite, and once you've got a real system for cycling back you'll start feeling less like you're running on a treadmill.
