When they say there are 12 pages, they mean 12 pages of actual content! In addition to the content, they've also included some cute pages that are empty so you can write your own notes and the end page is for inputting your own birth chart. I really like how they've included essential and basic information on houses, planets, signs, and aspects. Perfect for beginners and people who know a bit but need a cheat sheet to go back to. I kind of wish they added some info about synastry with another person's chart, but since that's a whole other realm of astrology info, it's understandable why it's not there. It would be a great topic for a secondary cheat sheet listing though!
