So I've decided that I'm taking Quantum Mechanics this semester but I'm not sure what approach I should be taking towards learning it. Our class is using the standard Griffiths text but after reading the first chapter and a half, although I like his conversational style and think that it's an easy book to read, I don't think it does a very good job at motivating/talking about the physical consequences of the equations he's writing down. I think that's something which i definitely need, as I didn't take a modern physics class before starting Quantum. So I borrowed a copy of Shankar from the library, whom I am a fan of since I listen to his youtube lectures quite frequently. However the approach he takes is quite different, explaining the mathematical formalism first, and then going on to stating the postulates etc. Since my class is following Griffiths, would it be wise to study from Shankar, while skimming over Griffiths, just to make sure I'm not completely out of touch with what's going on in the class? Or am I better off just following what our class is doing and study from Griffiths? Are there any other good books which would be a good supplement to Griffiths? I also have access to the Feynman lectures. Thanks for any replies.
