Head-to-Head Comparison
PassTheBigABAExam vs BDS
PTB versus BDS is the classic BCBA-prep debate: live teaching and a beloved manual versus the fluency-drilling system with the pass guarantee. The honest head-to-head, and the volume option that complements either.
The Bottom Line
Choose BDS if you want the safest structured system: 3,500+ fluency-drilled questions, a claimed 98.5% first-time pass rate, and a money-back guarantee if you complete every module, at $399–$779 time-boxed. Choose PTB if you learn from humans: the six-week live workshop and the Study Manual are genuinely good teaching, at roughly $780 for the full stack, with tightly time-boxed streaming. Both are teaching tools more than practice banks, which is where C3RT’s 52,750 questions at $99.99/year (plans from $17.99/month) fits alongside either.

Where C3RT fits
PTB teaches and BDS drills to criterion, but both leave daily high-volume mixed practice uncovered: PTB’s mocks total a few hundred questions and BDS caps module runs by tier. C3RT’s 52,750 questions with flashcards, audio lessons, and reels at $99.99/year (plans from $17.99/month) is the practice layer that pairs with either, or stands alone for self-directed candidates.
Frequently Asked Questions
Is PassTheBigABAExam or BDS better for the BCBA?
BDS for the guarantee and its fluency method, the safest single choice if you will genuinely complete every module. PTB if live instruction is what keeps you studying. They are complements as much as rivals: many candidates buy PTB’s manual, drill in BDS or C3RT, and use PTB mocks as checkpoints.
What do these cost compared to each other?
As of July 2026: BDS runs $399–$779 by subscription length; PTB’s core stack (manual + workshop + mock) assembles to roughly $780. C3RT is $99.99/year (plans from $17.99/month) with twenty times BDS’s question volume, the budget-and-volume outlier in the field.
