ACST300 was much easier than people led me to believe. Almost nothing conceptually difficult, although the general insurance module was hard to follow. I think that was mostly the Insurance lecturer's vague way of explaining things though.
If this unit fits well with your program or u want to work in insurance or super, don't avoid it because of anything posted on this site. I almost gave it a miss because of some horror stories I'd heard but I'm glad I didnt.
BTW Im a applied finance student not actuary and its bs about actuaries being fiercely competetive and this unit will ruin your GPA and all that. ACCG353 is much harder. FIN310 is harder. ACST300 is probably on a par with ECON335 in terms of difficult- only more reading (but not that much considering it is a 3rd year, 4 credit point ACST unit with no maths).
