Intelligence: High. Although degree of education is unknown, he is a battle genius, one of the biggest prodigies in the history of his warrior race. Since he is actually quite a calculating combatant (although not usually shown) it was pointed out by Whis how Vegeta's tendency to think too much actually held him back in direct combat.
