The Big Fat Notebooks are going to high school! Published just four years ago, the Big Fat Notebooks—with nearly 4.6 million copies in print and sales escalating every year—revolutionized the study guide for middle schoolers. Now this lifesaving series is ready to graduate.

Announcing the first two titles for high school students: Everything You Need to Ace Geometry in One Big Fat Notebook and Everything You Need to Ace Chemistry in One Big Fat Notebook. Designed as the natural next step for the savvy students (and stressed parents) who made Math (over 1 million copies in print) and Science (over 1 million copies in print) the bestselling titles in the middle school series, these books offer a world of help for two of the tougher classes facing most high school sophomores, geometry and chemistry.

Using the same formula that made the middle school series so successful, these new high school titles tackle difficult subjects in a lively, memorable, intuitive way. Critical ideas are broken down and clearly explained. Doodles illuminate tricky concepts. There are mnemonics for memorable shortcuts, and quizzes to recap it all.

Chemistry is one of the most feared subjects in high school, but fortunately National Science Teacher Award-winner Jennifer Swanson is here to break down this daunting subject into accessible and memorable units, from how to conduct an experiment to the Laws of Thermodynamics.

Big Fat Notebooks are already helping millions of middle school students. Now high schoolers will enjoy and benefit from this kind of brilliant help—a set of notes, as if from the smartest kid in class, to help them study throughout the year, get ready for challenging exams, and know they have a source to turn to when they need to catch up on missed problems or understand the most difficult or confusing concepts.
