I'm autistic and a significant percentage of my schooling was ignored by me because it held none of my interest. I practically made it a point to intentionally ignore certain information because I didn't see myself having any use for it in the future because I just didn't care about those things.

As it turns out, the part of me that cared about those things just had a stunted development and was behind. Certain subjects like language and history have an emotional and cultural significance that cannot be appreciated through only math. I highly doubt anyone could have explained this to me because I had thought that I was the sole decider of everything ever in my brain. I honestly probably still do think that way.
