Hello, I am sorry to bore you for another thread like this....But I at least I am not posting this on 'General Physics' threads. Soon, I will be taking upper division E&M and Classical Mechanics and Quantum Mechanics. So people said they are 'insane' classes and taking all three of them at the same time is like killing yourself. Is that really true? Well what do you think of that? Another question is......my friend told me that I should take upper division linear algebra before I start taking Quantum Mechanics but I can't really trust him. What do you think of that? One last question, I know I will be taking one year of Mathematical Methords classes (for it is required as a physics major), But I am thinking that's just not enough math. So same friend I mentioned above told me that I should take Real Analysis but I can't trust him. I want to take Advanced Calculus instead of Real Analysis but what do you think of that? Please, end my misery.
