econs can mah, physics got pure physics can already, chem who
says need a math, i use e math can already, statistic e maths more
relevant
BUT CALCULUS YES!!!!!!,
in fact, in H2 maths, almost all is A maths continued, only
statistics can be of emath stuff, so if no A math, you will get a
super hard time touching on differentiation, maclaurin expansion,
functions eg (For J1 lah)
Hence, give up POA and go for A maths, is more important
I'm guessing that you have not ventured any further than A
Levels. Otherwise you would not have said what you just said.
Advanced economics at university level requires some advanced
mathematics for mathematical models in economics. And that includes
calculus. No joke.
Advanced physics requires a good grasp of maths as well.
Einstein didn't create general relativity without the use of
tensors. And much of Physics is impossible without your wonderful
calculus.
All disciplines of Engineering requires both advanced Physics
and Mathematics.
I did not go beyond A Level Chemistry, but dollars to donuts say
that advanced maths is still needed for that. Oh wait, I did take a
couple of uni modules in this - you need some heavy-duty
differential equations in some cases.
