I've taken 1 course on quantum mechanics, and the only math requirement for it was concurrent enrollement in a DE course. My skills in differential equations are pretty good, but my knowledge in linear algebra is lacking. (I only know the basics to matrices, eigenfunctions, operators, etc).
The next one I'm going to take...I just want to be prepared for. If I have to learn linear algebra while learning quantum, it'd be like taking 2 courses 🙁 So I just want to be prepared.
And yes, schroedinger's equations are teh suck :disgust:
