Eiman.kuwait on "Wiley test bank and Yaeger.. plz help"

I failed AUD on my first attempt using Wiley text book and test bank.
I purchased Yaeger video lectures as the most recommended material .. But after watching Yeager lectures and then trying to test my understanding through solving Wiley test bank I get 60-65% which is really bad means i didnt understand anything and no matter how i repeat solving the MCQ's i get same result .. it just takes a hard effort. like yaeger didn't cover the necessary amount of material through his video lectures thats why i couldn't solve the test bank . do i have to switch into another review course ? and i know if i re-read the question in the test bank and dig the answer in the book i will understand and it will work eventually but it will waste more time and i will never be able to finish the material in a short period so please help me .. anyone used any material and it was good enough that you were able to get good results on wiley test bank or got you to pass the cap exam just tell me i will appreciate every response. thank you
