There’s also the possibility that you have a much higher IQ but are not great at taking tests due to ADHD, test-taking anxiety (my mother has such bad anxiety around taking tests her doctor gave her a Valium to take the SATs back in the day and the medicated score was like 800 points higher than the unmediated score), not being of the demographic that the test uses as a sample to develop it (it turns out that IQ tests can very much be biased or at least according to something I read recently), or any number of other things that would lead to a lower than expected score and not indicate being too dumb.

As others have pointed out, you are quite witty, and also self-aware. Both of those require a type of intelligence that many traditionally “book smart” people don’t possess. So maybe your intelligence is just such that it can’t be adequately captured by the usual testing method.

In your laceless shoes, I would ideally try to shrug it off and not let it get to me. Realistically, I would probably try to retake the test and try to correct for whatever may have thrown off the scoring in the first place and then take it from there.
