Since I tried to take the practice test at the end of the manual and I'm now completely demoralized and discouraged, I am wondering where I can get a free exam simulator. I checked online and haven't found one. The onein the manual is structured NOTHING like the Unit quizzes. They are designed with the expectation and each and every detail of the reading, will be memorized perfectly. I started confident and quickly lost it. Will now need an extension to continue reading................UGH!
