Passed

didn't do as well as I wanted to (810) but a pass is a pass, all I used was Darril Gibson's book and 30 days of practice exams. I read the entire book in two weeks, spent another two weeks doing practice exams, on questions I was missing I would go back to the book and use some professors Messer video, I was hitting 97% on the practice exams.

very few questions in the real exam are not anything like DG's practice exam but its a good way to test your knowledge, you will have to know this stuff to pass, not just remember answers to questions. with that said, here my advice.

Buy Darril's book, read all of it, work the practice exams and don't let a lot time laps before taking the exam
