I have taken the new SAT, and I got a 1380 combined but I know that if I re-do them this December, I will get a higher score. I have also taken my A-Levels early and I got two A’s and an A*. I considered taking the subject tests this December as well. Is it more advantageous to re-take the SAT or to do the subject tests instead?
