Well, if you can at least remember why reading into standard deviation is important, that will definitely help you when reading admission statistics. lol I felt that way when I finished Stats the first time, but the thing with stats is that you actually go over it again and again. If you took another Stats class in the future, you would be surprised how easily the things you actually put work into would come back to you. Advanced stats is basically concepts from elementary stats put into a nut-shell and done on itself.
It will come back if you ever get to doing research.
