I bought this book because I'll need calculus 1, 2, &amp; 3 for my major and I wanted to self-study ahead of time because i had never taken calculus before.<br><br>Like other reviews mention, this book has instructions, practice problems, and step by step solutions. It does not include theory or anything conceptual, for example you'll learn how to find the definite integral of a function but you won't get an explanation of what a definite integral is.<br><br>This may sound as though you need background in calculus before attempting this book, however that is not the case! I went in with zero background, started working through the book following instructions, and learned how to solve all the problems all while knowing nothing about the significance of each correct answer.<br><br>It may be counterintuitive, but learning how to solve calculus problems before learning calculus itself actually made it so much easier for me to grasp both components. I recommend considering this backwards method if you're like i was with no background, finding the solutions to these problems involves memorizing several rules and being proficient in algebra &amp; trig, that's it.<br><br>Some of the theories and concepts in calculus can be difficult to wrap your head around on a fundamental level, but it's easier when you're not simultaneously trying to understand abstract concepts while also learning how to solve practice problems involving them.
