I have actually been trying so hard to understand it, but somehow it's just not sinking in... :'(
I know that beating certain Pokemon give you certain "points" in whatever stat they're highest in (starly = speed stat), and when you level up those points go to that stat and raise it.
I have no idea how to calculate IV's, though, and I think understanding that would help a lot in my understanding of EV's..
I think... :P
I'm pretty uneducated on it.
