Using Analyst Notes to study

Has anyone every used the company Analyst Notes to study fro Level 1 and if you did what did you thank and is it worth the $99?

I’m using it right now. I like it because I can read through the notes and answer questions on-line at work. If I had to do it again though, I would’ve gotten the cheaper version since the e-book isn’t working on my computer. So far, the questions seem pretty good and almost every question has explanations and user feedback.
