and the same instructor teaches interactive courses from time to time through Barnes and Noble University

Personally, though the interactive version has a lot more to read through (fellow students' postings), I found it much more fun and intriguing because others came up with questions that I hadn't thought of and the author readily answered everything put to her. My only problem is that now I can't seem to stop buying new decks!
