(5+ stars) This is THE BEST Calculus study guide out on the market! It is clear and thorough, and you will seriously ace your Calculus class if you read this book...I'm not kidding. The authors make the stuff fun, but not in that talking down to you cutesy way that makes you want to vomit. If you go to class and come home scratching your head about what the teacher was saying, just read the appropriate section in this book and you'll suddenly go "Wow! This makes perfect sense! Why the hell can't my teacher teach like this?!?" There is also another book in the series about the rest of Calculus which covers the second half of a year or so. I also highly recommend that book. Anyway, just get this book and read it. Calculus will make SO MUCH more sense! Even if you are an A student already, this will really cement the concepts in your brain enough so that you can turn around and teach other people what you've learned! I'm not a math geek, but I give this book 5 stars! And, yes, I did get an A in Calculus! ( )
