I passed my licensing exams, but that wasn't due to AD Banker. I felt confident going into the SIE, since I was scoring 90% and above regularly on the practice exams, imagine my surprise when I encountered material I didn't recognize (far more than the 10 extra questions FINRA throws in that don't count) and felt like I passed by the skin of my teeth. There are not enough variety of questions in their practice exams, so repeatedly taking them has little benefit. I ended up using AD banker books for initial information, but switched to Kaplan Q-Banks for the practice exams since they had thousands of questions that exposed me to concepts not in the AD Banker books, and that way I was actually prepared.
