Regardless of any of these gimmicks, when a student from secondary school applies to university, the admissions office adjust the academic standing based upon what school the applicant attends.

Grade inflation is already rampant in the system.  For example just look at the explosion of the number of Ontario Scholars.  Too many of these kids enter challenging university programs and then fall flat on their faces.  And when they finally realize that they are not the genius that everyone has told them that they are they tend to collapse mentally.

Is any of this really doing anyone a favour?
