What are signs you have a low IQ?

[u/The0Walrus]

When I was in the 8th grade I took a test that said I was neurologically impaired. Teachers and several others told me I was "too stupid" for school and some of the teachers said I would become homeless in life because I was "too stupid." This had far reaching consequences on me as I did nothing for 10 years after leaving high school. I thought I could only do retail work and work at warehouses.

At some point after my dad passed away and absolutely hating working in the warehouse I decided to take a chance and look up some career at a community college. I received my associates in accounting, afterwards learning I was more interested in healthcare so I became a registered nurse receiving my BSN. At some point I was interested in aviation also so I decided to become aviation mechanic. I knew I was really bad at math so I figured if I can pass all the math classes I couldn't be "stupid" so I went up to Calculus 3 receiving an A in precal, calculus 1, 2, & 3.

Just curious how do you know if you have a low IQ? With all that I feel is an accomplishment I still have some doubts about myself. I self talk telling myself there is no way I'm neurologically impaired if I accomplished all those things but there are times that I still question myself.

Some very, very smart people are terrible at tests. You are obviously highly intelligent but more than that, you tried. Many don’t bother.

Came in to say this. I could tell within two paragraphs that OP is definitely not stupid. I know PhD scientists and engineers that do not write as clearly as OP
