Our education system is flawed, in many ways.
High School Diploma = Failure to use your brain.
Pursue further education or learn a trade.

When I was in 10th grade, I was doing math/history/english work that I had learned in 5th/6th. It was a joke.

IMO: Schooling up to 9th grade should be basic education, and 10th-12th should be about developing skills for jobs and maybe common sense if it is possible to be taught.
