When I was 13+ I took an IQ test and I got 141 but I took one again last year and got 128? (can't recall, 120+ range).
So I was surfing reddit and chance upon https://test.mensa.no/ (did some googling and people say this is probably the most "accurate" free test.) and got 125.
Was just wondering do IQ changes? I mean it does right? Fluid and all. However for it to be so drastic 141->125, it could also be the iq quiz I took when I was younger could be from a less reliable source
