I have taken and passed the courses you need using IC and minimum outside website practice quizzes. That said, it was a risk, but it paid off as I passed all 4 with a B or higher. This may not work for all, and if you try this method, be sure to know the information inside out and TAKE AS MANY PRACTICE EXAMS AS YOU CAN FIND. It really comes down to comprehension levels and interpreting the test questions correctly.

Now that I've passed these, I'll second what the others have already posted, study as many sources as possible. In the end, only you will know if you're ready. As I prepare for my finale two, I find I have the same apprehension you have. I look forward to the day I don't have test anxiety as a constant companion.

Please do a search on the subject you need on this forum, most of the info you're requesting has been covered extensively already. I know, because I had to do the same thing. Good Luck, Lee
