What I remember is that I would always be scolded by my teachers for not doing well. A few of my friends, however, who were black would never be scolded for not doing well at school.
The point I'm trying to get across is that racism can be quite subtle and baked into things we don't even realize, like the expectations we have of other people. I'm not sure how well I would've done in life if people implicitly expected me to fail.
