well, i think it's very different..
of course you have to use h2 maths knowledge (integration,
differentiation etc)
but most of time the topics are focused on proving and qualitative
questions
btw there are various syllabuses you can choose from (depends on
whether the jc offers it)
theres MOE, NTU, NUS if i'm not wrong
i took the MOE one and the topics are differential equations, graph
theory, combinatorics and plane geometry
my school didn't teach us plane geometry though cause you can
choose 2 out of the last 3 topics in the a levels paper (in other
words, the school chose for us)
graph theory is mostly about proving and qualitative questions and
modeling of real life problems
differential equations is mostly about population growth models or
concentration models etc.
combinatorics is something like permutations and combinations
(P&C is a subset of combinatorics)
