118 practice questions across 8 topics, every one with the correct answer, an explanation, and a link to the primary source it was checked against. Nothing is timed and nothing is hidden: these are the sets to work through when you want to study a topic rather than test yourself on it.
When you want the timed version instead, every free PTCB quiz draws from the same cited question bank and randomizes on each attempt.

12 questions with answers
Refill and transfer rules by schedule, plus the DEA forms and the recordkeeping each one covers.
Read the question, decide your answer before you look, then read the explanation whether you got it right or not. The explanation is where the transferable part lives: the exam rarely repeats a question verbatim, but it reuses the reasoning constantly.
Work a topic here until the explanations stop telling you anything new, then take the matching timed test to check that the recall holds up under time pressure. Pair them with the 2026 PTCB study guide for the underlying material.
