Which score?

So far have received these scores on my exams…

31C (32E 32M 30R 28S) & 30C (32E 33M 29R 27S)
1930 (590 CR 680 M 660 W) & 1900 (640CR 630M 630W)

I took the Oct SAT and am kind of sure I definitely did better on that, so I will probably send those when they come. I am going to send in the 31C score. Would that be the right decision?

Yes. A 31 is better than a 1930

thanks @wisteria100

Look at it like this: 30 of ACT is equivalent with 2000 of SAT, and every 1 point of ACT accounts for 60 points of SAT. So 31 becomes, more and less, similar to 2060.
