For students who don't come from "privilege" it was sink or swim, and those who survived the waves actually deserved their badge of honor. But for students whose parents were "fortunate" enough to send them to private school, they became a part of a corrupt system, whose only incentive is to have its students pass the national exams. Most private schools had high graduate rate, due to them bribing testing officials to allow cheating.
I was one of those privileged students who went a private school, who passed the national test without even reading a single question. I paid the price for it once I started college in the US. But unlike my origin, I had a chance to take a break from college and recalibrate my brain in a sense and find joy in learning.
If failing were normalized and did not have so much social stigma or financial implications (to an extent), we would produce more educated people instead of once just chasing credentials.
