Pure maths is a continuation of Additional maths in HKCEE
pure maths = algebra+calculus
for calculus, most of the stuffs are differentiation and integration
for algebra, u'll learn sth like logic, determinant, partial fractions, but alot of proofs are needed to be memorized.......
Maths & stats is a very easy subject I can say
u'll know normal distribution, probability, iteration, Differential equations, etc
For computer, i have no idea on that
