HI Megan,
I was trying to do this as well. However, It's a bit challenging.
Prep cast does not simply regurgitate. If you notice the lectures added more content topics than the book. Once you started watching the exam content outline you would notice some of the discussions will be in the
book by then, that's where I noticed it's all over the place. I emailed them and their respond is just follow the process with their PM study guide.
I also noticed that you would learn along the wait even if the topic is planned to be discussed at the later part of the course. Even in practice quiz questions. I am getting agile question in the random 20 questions even if the course have not discussed much about Agile. I am getting some paralysis but just keep moving.
