Thanks exactly what I did to study, The online tests and the practice exams in the book. I took one before studying at all, then from there assesed what I needed to focus on. You will be fine. Remember, if you need to take it a second time you have a waiting period in between tests so make sure you leave yourself enough time in case you do need to retake it. But you only need a 60% so it's not so bad. Good luck!
