I know there are a lot of similar questions here but just hear me out. I am going to start self-studying quantum mechanics in a few days. I think I am going to use the MIT quantum mechanics 1 lectures as a starting point. But books will be essential as I spend most of my time in school. I have squared in on Shankar, Feynman Lectures Book 3, Resnick, and Griffiths as my books. Budget is not a problem as I could find cheap editions available here. My questions are : 1) In what sequence should I read them so that I can have a good understanding of quantum mechanics and at the same time, a good amount of mathematical prowess? Or should I read them in parallel with each other. 2) I don't have a complete understanding of linear algebra. I understand stuff like determinants and matrices, but not very proficient in eigenvectors and eigenvalues. Is the linear algebra given in Shankar enough? Or should I master the text by Gilbert Strang? 3) How much of knowledge of differential equations do I need? I have read the first book by Apostol, so I am comfortable with stuff like linear second order differential equations but don't know the complex topics such as Legendre equations.
