Latest date to take SAT ii's? (for RD)

Hi Everyone!

I am an applicant from the class of 2017 (2021). I’m in a bit of a bind here - I’ve taken two subject tests already and got 800’s, so I am hoping to only send those scores to my ED school, which only requires two subject tests and does not participate in score choice. However, I need a 3rd only for GU.

My question is, would it be possible for me to take another subject test on the November date (after my ED deadline), and ensure that it gets to Georgetown on time? I am nervous to ruin my test record for Penn in case I bomb in October, but want to fulfill all requirements for Georgetown!!

Any advice would be appreciated!!

Fairly certain you can take the January test and still be on time.
