E-maths has always been an easy subject to score. Those students
in Raffles or Victoria will most probably be getting an A2 or A1.
So if you suck at E-maths, you got to pray hard that you can
pass.
I got an A2, so I am safe. 
What to do? Die die must have at least a pass in any maths to enter
poly, there are some exceptipons though. I believe if you have a
choice between poly and ITE, you will most probably not pick the
latter.
