Well I haven't done 4unit integration yet(only 3unit), so i can't comment there.
I used to hate complex numbers till a few days ago when i started to study harder, and revise all of complex numbers, it just comes to me easily, which is very good.
Graphs, ah graphs, the topic where you can score easy and one thing i like FAST marks. In the game of time in the 4 unit exam, graphs does help to get back at time.
Conics, ha, what can i say, its alright at the beginning but when you get to those really advanced parametrics, my mind starts to get scared, all of those trig substitutions, i dont know how people memorise them, hmm, im going to go have a think about how i can memorise em, hmm, cards maybe.
Well thats my two cents. Cya guys, good luck with 4unit.

Conics in 4u is mostly about ellipses and hyperbolas. If you've done parametric form of the parabola in 2/3u, then the questions types should be familiar to you.
It's considered hard because it generally requires alot of algebra bashing to get an answer.

Integration is always the easiest topic... and generally is a gift question. I mean, considering how many integrals you will do as practice up until the HSC, you will be so proficient and drilled in them that you will be able to solve them without application of any thought at all. Similarly, graphing and complex numbers will usually be very doable, as with polynomials, and to a lesser extent mechanics.
What will kill you is the conics, which generally is just an evil, evil algebra bash, as well as the 'harder three unit', the deceptively named topic that will result in some bloody annoying geometry problems.
From experience, if you are so lucky as to get a paper with the first 4 questions being complex numbers, polynomials, integration and graphing you can knock those out of the way by the one hour mark.
