Ugh. Not fun. But, I have been passing my tests so it seems to have been doing its job.
Make sure to check out the corresponding Ballast mock exam books if you feel like you have too much self-esteem and need to be taken down a few notches.
One of the better ARE prep tools I am using. I recommend reading both this book and the books from the Kaplan series, because while the Kaplan books give you more information, Ballast breaks it down to the most important subject matter you will need for the exam.
A necessary evil - but I really think it helped me pass my exams! Although some of the material was over-detailed, it covered a lot of necessary information. I started every new exam study marathon by reading this book.
