I just used this text for the first time while teaching an undergraduate course in QM. It is now my favorite QM book and I plan to use it from now on.<br><br>The main attraction for me was the large number of worked examples and the practical leanings of many of the calculations. In both of these traits it is better than Griffiths' text, which is what I had used most recently.  However, I soon became a fan of the text style as well: Zetilli is very readable and straightforward in his presentation and covers all of the necessary historical and mathematical background (which may be shortened or skipped if the class has the math skills already).  While there were some typos, most should be caught by the instructor (or perhaps a sharp student!).<br><br>Other books I have used simply jump right into the Schrodinger equation or relegate some of the important calculations to the homework with no comparable examples in the text.  This can work if the instructor is willing to go "off-book" frequently to fill in the gaps but can be frustrating to a student working on his or her own.  Each chapter has numerous "examples" in the text, with end-of-chapter "problems" (with complete solutions) and "exercises" (unsolved, though there is an instructor's solutions manual). This makes it much easier for students to find a model for the type of problem they are learning how to solve.  In fact, I often listed helpful "problems" every time I assigned "exercises," which my students greatly appreciated.<br><br>I strongly feel that one skill that faculty should cultivate in their students is the ability to read - really read - a text book on their own and learn from it.  For an undergraduate course this is a self-contained book that will serve as a valuable reference for self-study.  It is very readable and I expect that the students will be happy to have it nearby when they take QM in grad school.
