Version 2.0 is recommended for students who prefer the most updated visuals and additional practice materials, but it is not required. While we’ve added some additional content, updated examples, and refined the index, the core material remains the same.
If you currently own a V1 6th Edition PTB ABA Exam Study Manual, you can study with confidence, as the information is up-to-date and accurate.
For this reason, we do not offer exchanges to V2 for customers who already have V1.
