thats so dumb
my school did "compression" classes as well but only top ranked students could be in those, students not doing well were dropped to the regular pace classes for their own sake + there was the option to drop out voluntarily
I did 3 hsc subjects early but some of my cohort did 2 or 1, or none, basically there was a choice with it, as there should be
crazy that there are schools forcing the whole cohort to compress that's surely gotta be the perfect way to drop the schools rank and sabotage students
