I will be applying to MIT and Cornell, both of which require a science subject test, by the regular deadline. I plan on retaking the chemistry subject test in December (1st attempt was rough). Should I wait until I receive those scores at the end of December and submit everything at once? Or to be safe, should I submit everything else a few weeks before the deadline and submit the additional subject test as soon as I receive the scores? I don’t want to have to pay twice for reports going to the same schools, but I also don’t want to risk having my scores not be received in time…
