"It's incredible. He got every question right perfectly. No muss-ups, no missed carrys, even though he used some kinds of notation I've never seen before. I watched him breeze through the arithmetic and geometry sections. He only slowed down when he got to the algebra, and even then, I could tell it gave him almost no trouble at all. There are even a few very simple trigonometry and calculus problems at the end of the portion just in case, and he got those perfect, too. He's at upper secondary school levels, maybe higher."
