High school preparation for US student looking at Oxbridge/Imperial

I agree. If he’s going somewhere as demanding as Oxford/Cambridge, I don’t mind him repeating material he’s seen in high school.

He’s done a couple AOPS classes, although they were a couple years ago now. The Intro to Number Theory was one of them, which he liked a lot. Could look at the Intermediate Number Theory class.

Thanks — very good to know.

I see the cost difference on Oxford’s webpage, but both the Maths and Maths/CS pages seem to say 3 years for a BA and 4 years for an MMath (or MMathComSci). It’s very possible I’m misunderstanding something, though.

Thanks for everyone’s comments — they’ve been very useful to me!
