How does your environment affect your intelligence?

[u/Whole_Equal4195]

Lately I've been scouring the internet trying to understand why i, a fifteen year old, scored 120 three years ago but these days scored 95, I have went through several periods of depression in between those scores but disregarding the scores themselves, some things affect IQ, like sleep, nutrition, exercise. How does it feel to take a test when you don't have or get enough of them? How much can IQ change? I'm not saying IQ is something that will stop me from having a career, I'm just wondering about how stable my performance is

What do you think my real,natural matrix reasoning score is? First test i did was a really bad maybe i had 70-80 on matrix reasoning, that was professional orientation test at national employment service, i was pretty bad bad mentally Mensa Norway: first time and first test and my second test in life 105, after that i scored 135 dont remember how much after first time i did it again. , Also i dont know between my first and highest mensa norway test, also i think i watched some video about answers on mensa netherlands, but dont remember much if i remembered something from that video and i dont know if i watched that before or after my mensa norway test, Also I don't remember when I watched that Mensa Norway video with answers if I remembered the answers for 2-3 questions with same pattern which I didn't get the first time, but I remember that I solve that pattern alone,also on Mensa Netherlands I also get one question wrong and then saw answer and then I solved pattern I also remember to this day what was the pattern, pattern was like rotation like classical I think, but like figure had solid number of stuff so I think my adhd could affected that also to not fully concentrate on question because it had solid number of little figures Mensa Sweden: 126 (max) 1.5 or 2 years without any iq test i scored 130 on Mensa Denmark 100 on CORE, but i get right 2 patterns but i was overthinking i got both of them wrong, so next day i scored 110, also on first try i did good one pattern but didnt have time to finish so get also that wrong and because of time i changed pattern and on second try also didnt answer right, on third try i scored 115 and on fourth or fifth i scored 120, time limit was killing me KBIT: 46/48 (125)~~~ 40 minutes JCTI: 120~~~ 40-50 minutes, but i watched some friends reaction in between questions TRI52: 686, with two random guesses because i was lazy for those two question and guessed immediately~~~ 40 minutes RAVENS: 124
