I expected a little more accuracy out of this program. After spending $199 dollars on audio lectures, a study guide, and practice tests, I have found numerous spelling and other errors that make the questions hard to understand. I have also found answers they deem correct that contradict the ACE textbook. I appreciated the audio lectures helping to explain some of the more tedious aspects of the textbook but to be honest I would spend this type of money again if this was the program I was going to get.
