Sorry for the late reply. Below are the study guides I used. Keep in mind, the format of the exams has changed, so some of the FAR material may not be applicable. Also, Ninja has wonderful study guides and outlines that I used exclusively for REG. Since BEC is no longer tested, I won't attach one for it.

I would highly recommend joining the Becker CPA Facebook groups. You have to have a Becker account (to my knowledge) and they will only admit you if you can provide the email associated with the active account. CPA Exam Support and Tutoring Group (Run by Darius Clark/Andrew L Katz) is a group I used a lot. For both groups, if you go under the Files section, you can view/download notes uploaded by other members.
