I remember Geometry as being the second most boring class in high school, Algebra being the worst. I got this oracle because I liked the look of the cards. Not pretty pictures of kings and queens and knights, like a standard tarot deck, but simple geometric forms that kind of glow and reach out to you. The exercises in the enclosed book are simple to do and put me in the mindset of a ancient geometer. With a few basic tools--pencils, straight edge, etc., you can draw all the forms illustrated on these cards. I'm sure you can go deeper into this subject, but for a novice like me, this was great beginning. As for being an oracle, I am not into divination and do not use it as such, so you're on your own as far as that goes. My main gripes are that the box it came in started coming apart on day one, and I had to find another box so I wouldn't lose my cards. I also think that the book was missing a page. This book-card set is not like a tarot deck, but is for those who like a hands-on form of "yoga." If you are into yantras or mandalas, you might give this a try.
