I didn't get a CS degree precisely because I bombed out of math so bad in high school that I couldn't get admission to any program. Here in Canada a good grade in academic-stream high school math was simply mandatory for admission to any BSc program. Took a philosophy BA instead, though didn't finish it... dropped out to go get a job programming during the .com boom, and now 25 years later I work at Google.

Was a long road, and would have been a lot less torturous if I had been better in math. Not because I've needed math much in my programming career, but because my bad math became a reason that gatekeepers closed doors on me over and over again. Perhaps the strongest cause of imposter syndrome I have at work is less related to not having a CS degree -- because I feel like I know about 99% of the content of any CS program -- but more to do with the fact that I work around a lot of maths geniuses.

In reality the "math" I failed in high school was more arithmetic than mathematics per se. I feel like I might have a disability around numbers but I've rarely had problems with the higher level symbolic manipulation involved in algebra or programming or symbolic logic, etc. though my probably-ADHD means I have to really step back and work through things at my own pace in my own environment, and so whiteboard coding type interviews really piss me off.
