The book is structured like the destroyer, but as you know concentrates only on organic chemistry. For chapter outlines see the website. Not only are the questions good, but the solutions are also awesome....every solution is extra detailed and jammed with extra pieces of knowledge that come in very handy.
Whereas most books just teach you organic chemistry, the odyssey surpasses every organic chemistry learning tool on the market in that it develops your organic chemistry IQ for standardized tests. This book gives you great insight into HOW organic chemistry questions are developed. Stereochemistry, Elimination/Substitution reactions, and synthesis problems are key areas where textbooks fall short in teaching you what to know....because what you need to know can't be read but must be honed and cultivated through problem solving. This is why Odyssey is a must have for anyone serious about organic chemistry.
This book is very comprehensive, but don't think for a second that by studying this book you will ONLY be studying chemistry....by mastering this book your knowledge of Chemistry as a whole will be more complete....the acid/base chapter is great by the way. Anyways...hope that answers any questions you might have. Good luck
