Big Mock Exam


The original Big Mock Exam has been upgraded with video segments to offer a highly individualized, in-depth review, while simulating an authentic test experience. Designed with a commitment to academic quality, the mock exam integrates clinical and scientific language, and reflects the format and distribution of questions on the actual BCBA® exam. The score report now features 175 video reviews that correspond to each test question, providing comprehensive explanations, detailed breakdowns, visuals and rationales allowing students to shape the content to their particular needs.

Access begins immediately and expires 6 months from the time of purchase. To avoid a false sense of improvement, PTB has limited the exam two attempts within 6 months.
