Excellent coverage and hand-holding explanations of what will be, for most undergrad physics majors, their first truly difficult class.  Morin knows from the outset what things will be confusing and tells you not to worry, the full meaning/import of a definition or equation will come later in the chapter or else he just explains right there after introducing it.  Compared to Marion and Thornton and Goldstein, Morin does the best job of introducing Lagrangian mechanics, angular momentum, special relativity, and orbital mechanics I've seen, even if at the time I was taking my undergrad CM the material seemed REALLY REALLY difficult!<br><br>The examples in the book help you solve the end-of-chapter problems.  Many of the worked-out problems are very good preparation for graduate preliminary exams for CM.<br><br>It is essential to understand every example problem and worked-out example, and to be able to solve a lot of the solution-less problems as well.  When I took CM as a grad student this book came in very handy.  It's somewhat more advanced than the more common undergrad CM texts, and introduces a lot of concepts that Goldstein covers in a very obtuse, formalism-laden way.  I think this book is very very good preparation for Goldstein.  Even if you are past your undergrad class and about to take a Goldstein-based CM class, buy this book and refer to it often.  It's only real weakness is the less in-depth coverage of Lagrangian and Hamiltonian mechanics as compared to Goldstein.  There is a freely-downloadable extra chapter on Hamiltonians on the author's web site, which helps to make up for this a bit.
