Sure, why not? We don't even know his grades or what his academic talents were. Also, while it's a fine course of study, it's not a Master's degree in particle physics or something. It's designed for recent high school graduates. So assuming he graduated with good standing, I don't see why he couldn't have done it. You sure don't know that he couldn't, for a fact!
