Should I take abstract algebra. I was going to double major but I don't want to be at school for more than four years or pay for extra classes. Therefore, I decided minor in mathematics instead. I registered for abstract algebra before I decided to just minor in mathematics. I have a hard time registering for classes since the physics department hired a new adviser which is why I haven't gotten out of it yet. So, should I stay in the class? Will it be helpful for a physics major?
