Can I register for another SAT Subject Test online after I've registered for one?

Question

CAn I add a test later or must I do it at the test centre only?

Plus,I took maths 2.Is there any harm if I take maths1.There are colleges that take maths 1 in place of maths 2 and I think I'd do better at it.So,will they use the higher mark or will i be considered inadequate for taking a lower level test?

I mean,at colleges like Cornell or MIT(which takes maths 1 in place of 2,i chkd with their website)

Answer 1

If you are looking into Cornell or MIT, you should either take both math 1 and 2 and get 2 800's or just math 2 and get an 800. The math sat 2's have a large curve so an 800 is easier to achieve than it sounds.
