Explanation made simple for ease of reading, I recommend any undergraduate to take reference from while studying for their physics module. The price of these colelction is definetely worth it, given the amount of content available in the 3 books. The content it offers is way more than any other textbook I have in collection.<br>The quality of the hardcover and paper of the 3 books are good and durable.<br><br>However, the books does contain errors (language).
