Changing to Math as first choice major from something very different

Not sure where to even ask this one, but S20 just decided that he wants to pursue what he listed as his second-choice major (Math). His original first choice was Music, and he’s auditioned at several schools. IMHO, he has much more of a comparative advantage in math and applied math (e.g., Physics) than he does for music. For example, he has 800 on SAT Math and on Math 2 Subject Test, and he’s in AP Calculus and AP Physics and rocking both. He took AP Stats, last year. He already contacted our large state university, to which he was initially admitted for Exploratory (and Honors), but hadn’t yet heard audition results. Will probably be awhile before he gets a response from them. He will contact the schools to which he applied RD, which are highly selective and both reach schools. The other schools, he applied to only b/c of their reputation for music.

Any words of wisdom? Anything we should be doing? Anywhere that’s great for math to which he could still apply? FYI, my B.S. is in Math.

Possibly a better place to ask is in http://talk.qa.collegeconfidential.com/math-computer-science-majors/ .

Or, if it pertains to changing to or declaring the math major at a specific college (before admission or after enrolling), try that college’s forum section. Math may or may not be a more competitive major, depending on the college.

In terms of college suitability, different math departments may have different subarea emphases, which can make them more or less suitable based n student interests and post graduation goals.

Doh! That’s where I meant to ask!
