Have they already announced state cutoff for VA? I got some info but not sure if that’s for class of 2027.
When would the cutoffs would be announced?
I am happy with his score but he was asked by some friends if he would qualify as a semi finalist.
What does SI stand for?
Answering my own question from a 5 year old Reddit post, Skypetutor says:
PSAT/NMSQT Selection Index (SI) score formula = [2(Verbal score out of 760) + (Math score out of 760)] / 10
For example, a perfect score of 1520 on the PSAT would earn you a 228 selection index.
2(760) + 760 = 1520 + 760 = 2280
2280/10 = 228
A score of 1440 with a perfect 760 on Verbal and 680 on Math would earn you a 220 selection index.
2(760) + 720 = 1520 + 720 = 2240
2240/10 = 220
Conversely, the very same composite score of 1440, with a 680 on Verbal and a perfect 760 on Math, would only earn you a 212 selection index.
2(680) + 760 = 1360 + 760 = 2120
2120/10 = 212
As you can see, the distribution of Math and Verbal scores matters quite a lot, given that Verbal scores have twice the weight.
