No, it's good - you want to EV train things in stats they tend to be good in!

Or go 252 HP/136Def/120Spd.

Hm, a good Pokemon to HP train? Yamask would be good. 252 HP and 252 Sp.Atk.

Each Pokemon has a set amount - use Bulbapedia Oh, why try with Pichu? Pumping a Raichu's HP up a lot won't hel pmuch as it doesn't have great defenses.

HP? not sure, it depends what Pokemon you plan on using, an obvious one would be Blissey/Miltank. Try looking on Smogon, they have some brilliant ideas.

And it is a lot - say a Pokemon has 300 Atk at Lv 100 at average. If it has an attack-raising nature, that'll increase to 330 at Lv 100. If it's been fully EV-trained, you've given it a whopping 393 Atk. You raised it by nearly a third of it's attack, just by EV training it and making sure it has an Atk-raising stat.

It can have a maximum of 252. Thus earning itself a stat boost of up to 63 points

I Pokemon has 510 EV's, but it's 4 points that give it a stat boost of +1. Otherwise you'd have Shuckle's with around 750 Defense.

But otherwise, you're right.

Hai!!!!!!!! So wutz up? 83

And yes, school does count for the Occupation thing.
