I'm a second year undergraduate student in Physics looking for a good textbook(s)/resource(s) to prepare me for my first Quantum Mechanics Class

Question

I recently signed up for a Graduate Quantum Mechanics class at my University for the Fall of 2021 and after doing some review of the notes that the professor made available to me, I'm afraid I will be a little overwhelmed in the class. This is my first class in Quantum Mechanics although I have taken Modern Physics (giving me some very non-formal introduction to Quantum Mechanics) and wanted to know what are the best resources for some self-study during the summer before I start the class. I'm interested in learning the notation, and motivation behind QM while hopefully gaining some fluency in the Linear Algebra that will be involved.
