I'm a second year pure maths major and i don't even know what a isomorphism and homorphism means.
Ever since high school I've been memorizing recent past exams (two years prior to the upcoming one and with similar content), and applying it to upcoming exam and I've gotten away with it for four years. I feel guilty that I don't understand mathematics, but boy maths is like the easiest major if you know how to cheat it. I don't even do problem sets.
Any /sci/ guys know this feel? Who here memorizes past exams and apply it to their upcoming exams?
I'm not a conceptual thinker btw.
