While I was able to turn off the annoying voice that "Read" to me. It was extremely irritating that I had to wait to click next once I read the text. I could read everything on the screen about 6 times in the time it took the stupid clock to tick down. I am smart girl and I can read quickly and learn fast...holding me to a set time per screen drove me nuts. I could have completed the course in about 3 hours if I had been able to read and click through at my own pace. Instead it consumed 7 hours of my time. The information was well laid out, clear and easy to understand, making it extremely easy to learn.
