JC = Advance O level, u learn about maths, eng, chinese,
physics, science again, at a higher level.
Poly is really depending on wad course u choose, im taking
engineering course, and i still learn maths, physics, electronics,
electrical stuff
Poly is not stress until u get projects, group works, etc etc.
Every lab session in my course is counted towards my overall GPA,
so u can say the stress is distributed out, only sometimes it
accumulates. SOmetimes a few test in one day, then stress free for
a few more weeks, then exam again
There is a lot of debate over whether diploma is better or A
level is better, but i believe no point arguing about it
