Query: Verbose

I used this book for the Cornell Econ 301 course, a calculus based intro to microeconomics. The professor taught everything in lecture so that the book was used only as a supplement. I read part of the book and found that it is too verbose and repetitive. The author could have explained everything in less than half of the book. The exercises are not helpful. Moreover, this little book is sold for more than a 100 dollars. Not worth the money at all.
