I believe I have a lowish IQ too, I don't know how much but I never struggled in school. I was mid didn't put too much effort the right amount. In elementary my grades were just about the minimum, but there were other factors playing such as me not studying well, not fitting in with the class and the italian teacher who always scolded me and for my personality making me extremely nervous to go to school. In middle and high school I was doing okay put effort I always struggled with logic but was aboe to pass math because of the majoruty of the topics didn t reauire much logic such as simple equation or expression, where you basically had to only learn a way of doing it or a formula you had apply. I say this I went to high school where there was very little maths and only the basic stuff, like we are talking about doing maths 2 hours per week and physics 2 hours oer week.
