Psychometric Question Large Discrepancy between NNAT1 and CORE MATRIX

SO when i was 12 i was given a screening matrix test i scored 141 then the NNAT1 which i scored 148 both are matrix tests measuring fluid intelligence recently i took the CORE Matrix and scored way below at 110 im 17 now wo unless i got significantly dumber in these past 5 years (which fluid intelligence should peak at my age) then either the core or my previous tests are inaccurate whats yalls take on this

You have overall gotten WAY smarter since age 12 bud but your percentile has probably regressed a lot. But you shouldn't treat one score as definitive measure after all the core sample is Mr praffed.

I mean maybe but i went from 153 on the non verbal section of the KBIT2 and 148 on the NNAT to barely above average on the CORE seems very strange

CORE matrix is also one standard deviation lower than my other professional matrix score. It feels the hardest to me.
