If you could get to a course, it would be better, that way is more interactive and you can ask question etc.
Julie is a member of my Alley, and she has done what her bio stated. Without being able to review the classes I can't say one way or the other. I know she's had a lot of experience, so the courses should be good. Personally I do better in real life situations then reading about it.
