Ebook: Problem Book for First Year Calculus (Problem Books in Mathematics)

The book contains all the significant problems for a first year calculus course. Working on these problems would dramatically help you gain perfect grades from your calculus classse. (At least that happened to me and my friends who use it.) No matter you are a math, physics, biology, or economics or even chemistry major, you would find it extremely useful. It also contains some very challenging problems up to the level of the world's most difficult undergraduate contest: The Putnam!
