Don't say just Primary School lah.....I have a sneaky suspicion that they have been adding nonsense to the curriculum over the years, encumbering the kids with useless things to learn. This makes them feel inadequate in school, which then makes them seek out tuition centres... their certification brings in more revenue for the govt.
Universities also.
Like a lot of the stuff we study in University is also useless from day to day perspective.
WTF I learn all the life cycle of various worms which don't even exist in Singapore? Or for me to study Dengue Fever when there is no such disease in Canada? Or half life and pharmacokinetics of drugs I will never prescribe or encounter in my practice?
I am sure same can be said for Engineering Accounting Law and what not
A lot of crap for the sake of teaching and giving teachers and lecturers something to do.
