The only restriction that I'm aware of is that if you are under thirteen years of age, net laws prohibit online registration (well, not exactly, but CB has apparently interpreted things that way), so you have to mail the application rather than registering the way most students do. We had to do that with a College Board test.


I can't say if 10 is magical in some way, since DD was older than that at the time.
