Does n = N ?

Before i make a real effort I want to be sure because it kinda looks like 
maybe you copied my "N" and then typed "n" when you meant "N".

If by "student," you meant "grad student," then maybe I shouldn't even 
try, but if you meant high school student, then I probably have some hope 
of succeeding.
