The basis for selection in school to the university?

There is a revealing article today på DN.se which was also discussed with the School Minister Jan Björklund present in Studio 1, on radio P1.

There are things I don't know about this game because Björklund suggested the remedy that they should test school habits in grading student against double checked national tests and then send in the police, i.e., Skolinspektionen.

Why not let the schools grade however they please and instead, like in the US where they have all kinds of schools, use the SAT score for selection into the university? No policing and the university get the students that are most prepared and able.

There is a Högskoleprov in Sweden. How does this relate to the SAT? It only is an additional mean of entering university. Used as a second chance. It must be better to use a yearly national test than using grades. Then schools can compete and we will see evolving good schools which produce kids that do well in university.
