Which Score to Choose?

2330 OldSat, 1470 NewSat, 31 ACT

2330 definitely

2330 old SAT. Congratulations!

for sure the 2330

No one ever mentioned the Concordance Tables to you?

all my classmates are taking the new one though… class of 2018

Go to the websites of the schools that you’re interested in and see what their policy is concerning class of 2018 and the SAT. Some may require that you submit the new SAT but if not, I would go with the 2330, regardless of what your classmates are doing (unless you feel you can score higher on the new SAT).
