SAT Essay Score Submission

I took the SAT in October and in December. In October I got a 1400 with essay scores of 6/5/7. In Decemeber I got a 1560 with essay scores of 5/4/6. If I want to go to a T20 school should I report both my scores so that they can superscore the essay or just send my December scores?

No T20 cares about the essay score anymore. Just report the December scores.
