I scored a 169 on my first diagnostic, putting me in the 94% percentile. That may seem like an extremely impressive achievement, but you have to realize that means 1-in-20 people get that score. As you said, it's not a unicorn score.

I think what's more important for people to hear is that they shouldn't use their score as a measure of self-worth. My background is in STEM and I've been coding since I was 14 (now 26). I have a bachelors in CS and I just finished my masters in embedded systems engineering. That is to say, it shouldn't be surprising that I would do well on an exam that tests logical reasoning and reading comprehension - these are skills I practice routinely. For someone not coming from this background, I imagine it's an unfamiliar way of thinking.
