I failed the 66 last monday with a 72. I used passperfect because I had used them for the 7 and scored an 83. I have taken about 35 finals before I went in for the exam, and although they definitely gave me enough info to be bale to pass. I did not master some of the material that was more prevalent on the actual exam. I had my pass perfect program reset so I can go through all the chapter practice questions, quizzes, exams, and mastery exams and finals. I also purchased TC in which I scored 84 on my first random final and an 88 in my first final exam. Can anyone tell me if I am in the right direction and if TC is really as good as everyone makes it out to be.
