I'll take a quantum mechanics course this semester. I am a so-called advanced undergraduate (3rd year). This is the second course of quantum mechanics for me. The first was "the basics" (no bra and kets, a bit of linear algebra). I have read a couple of reviews of books on advanced undergraduate books, like Griffiths, Shankar and Sakurai but I coudn't make my decision yet. I'm ready about the math (linear algebra, differential equations) but not Dirac's notation. Thank you!
