The goal of our broken educational system is not to teach.
It is simply a test of who can learn the most in the least amount of time.
What is being learnt is of little importance. it doesn't matter if it is useful or beautiful things.
The useless exams are set exactly at a difficulty level that produces a Normal distribution of grades:The difficulty is just set for your particular group of students.
- too hard and everyone gets 0, so you can't split people well
- too easy and everyone gets 100, so you can't split them well either
As Elon Musk put it:
I think college is basically for fun and to prove that you can do your chores, but they're not for learning
