When can I sign my son up to take the October 3 SAT?
The regular registration deadline for the 2016 October SAT is September 1st, so you should sign up before then. You can actually go online and register through your son's College Board account right now if you want (if he doesn't have an account yet you can create one here). And just so you know, the test is actually on October 1st this year, not October 3rd!
