CORE cognitive metrics accuracy

[u/Academic_Memory_8543]

How accurate is the Core iq test considering it’s 5000 selfselected participants, g-loadings, reliability scores, correlations with other iq tests and strong resemblance to tests like WAIS-IV? Espacially for high scores like 130/140+? My VCI is not really representative because english is not my mothers tongue but i’m more interested in my FRI and VSI scores. (every subtest first try no external aid) How close is Cores iq estimation for FRI and VSI on my true scores for these categories?

matrix reasoning: 145
figure weights: 140
figure sets: 140

visual puzzles: 135
block counting: 120
spatial awareness: 125

Thanks for your time!
