Using this and Gleim...I just passed the IRA with an 80% and right after took the FII and got an 86%. There were about 12 questions that I never saw from either studying source on the IRA. Overall, I started studying the Gleim book and watching the King videos exactly a week ago and passed two tests 7 days later. Felt like I could have done better on the IRA and most of the questions I got wrong were not in the King videos nor the Gleim book.
