So I took the October testing session for Math II. I haven’t gotten those scores back yet, but I just sent score reports to all the colleges I’m applying to with deadlines before December 1st. Would my updated scores be sent automatically, or do I need to send the Math II test separately when I get those scores back if I sent all scores with no score selection?
I am not sure what you have done. When you went to order scores, did the order section show the existence of the Oct test but with no score? If yes, then the only thing you actually did was order the Oct test, along with prior test scores, to be sent when the Oct scores are released, and nothing will be sent before then.
The only way you could have sent prior scores now was to go into a prior test registration which did not mention the Oct test at all and order prior scores sent. If you successfully did that, then no, the Oct test will not be sent to any college based on that order. You have to make a new order to send the October test.
I am not sure which colleges you are referring to with Dec 1 deadlines but if you wait to order scores sent as soon as the October scores are released (later this month) they will get to any college by Dec 1.
