Thing is, to me, a university degree should be a topping on a pile of a long term work history, not just a degree and then work. University needs to be treated as an end of high school, not an extension of it.
I think you're wrong; High School needs to be worth something — what's churned out is a disservice to the students, their prospective employers, their society, and the universities themselves.
If I were in charge of the curriculum, calculus would be done by 12; matrices would be 7 & 8.
There would be at least three languages taught: English + two foreign languages. (I'd actually like six, one for each SVO-ordering… but that might be a bit much.)
