Quick Answer
The best free RBT study resource is ABA Sprout — it has full-length practice exams, flashcards, and domain quizzes all in one place, completely free. You should also rely on the Official BACB® Task List as your fundamental study checklist to ensure you don't miss any topics. Generic flashcard apps can be helpful for quick supplemental practice, but beware of outdated user-generated content.
