The course was well layed out. Quizzes at the end of the chapter did not tell you the correct answer if you got it wrong. If you get less than a 70% you will need to reread the chapter. A few of the final test questions were not covered in the reading material. Its a 50 question test. Although I passes the first time around with an 86% you can retake it as many times as necessary to pass. Customer service is great and easy to speak with on the phone. Please note per customer service, you can retake the final exam a second time without re-reading the material. However, if you do not pass the second time you will have to contact customer service to reset the counter and re-read all material before you can take the exam. You will get 2 more attempts before you need to reset the counter again and so on. Lastly, the questions on the chapter test are timed. You cannot go forward unless the timer says so. It adds a bit of extra time since you can't progress. Many times I found I was waiting for the count down timer to end. All in all I felt it was a great way to get the course done online and would recommend the course.
