Hard Time self studying Principles of Quantum Mechanics

[glueball8]

Hi,

I'm currently self studying "Principles of Quantum Mechanics" by R. Shankar. (Its prep for research, a Prof. recommended the book.) I have only done 2nd year of intro to QM which only covers 1st few chapters of griffiths. (Know multical)

I find myself having a hard time going to Shankar. Does anyone know any online notes, video, books that I can look at while studying Shankar?

Thanks.

What is your specific problem? If it's the math, I'd say go read some linear algebra. Else, what I'd suggest is when there is a new physics concept given, check Wikipedia for a concise "big picture" treatment on that specific.
