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

I'm 12 weeks out from my BCBA exam and the volume of material in the task list is honestly overwhelming. I've been studying about 2.5 hours a day, 6 days a week, and I still feel like I'm barely keeping up with new content while forgetting older material I covered 8 weeks ago. My practice scores are averaging around 65%, and I know 65% is roughly passing threshold but I'd feel a lot better with 72–75% going in.

The foundational concepts and principles section feels solid — I'm hitting 78–82% there consistently. Where I keep falling apart is measurement and data analysis, and anything involving experimental design. Single-subject design questions are particularly rough because the variations between reversal designs, multiple baselines, and alternating treatments start to blur together after a while.

I also supervise RBTs as part of my current role, so the supervision section should theoretically be a strength, but I keep getting tripped up by the specific BACB ethical standards around supervision hours and documentation requirements. The ethics section overall is more specific than I expected going in.

Has anyone found a good system for keeping foundational content fresh while still pushing forward through new task list areas? I'm thinking about a 30-minute daily review of older material before new content, but I'm not sure if that's the right ratio at 12 weeks out.
