I'm currently a third year math student and I am preparing to take my GRE subject test. As I study for the test I feel as if I have forgotten much of the content from classes that I've taken in the past. I did well in all of these classes but I find myself having to go back and relearn things from DE, Linear algebra, Number Theory, etc. Is this common for math students or am I dumber that I previously thought? This whole situation has me feeling pretty low. I'd appreciate any insight.
