I thought AUD was challenging but pretty straightforward- still waiting for my score though so take this with a grain of salt. I used becker and thought they did a great job. Follow their plan. Do all the passmaster questions, watch all the lectures, do the readings and you will be prepared and do fine.
jeff: m still confused whether m in wave 1 or 2 for auditing coz my OASIS still says NTS have been attended but scores have not been received !! please advise.
