a soft subject is one that is very easy compared to other, 'hard subjects'. (e.g. any extension course, sciences excluding biology, etc...)
People choose them, despite their woeful scaling, thinking they can ace them so it doesn't matter. But it does. You lose your man/womanhood. You do your country a dishonour by reinforcing the stereotype that this is a land of slack anti-intellectual drinkers.
A list of soft subjects, for those who are a little confused:
-- Biology
Now, granted, I am trying to be at least a bit inflammatory, but, my good people, what are your thoughts on these soft subjects and the ninnies who do them? (They're off the hook if they have some sort of mental impairment, God bless them).
Should we force them to do real subjects like physics and maths, and English extension? (Though physics is slowly becoming more and more like a humanity subject).
