mod 1: principles of sciX (mostly philosophy ngl, occams razor, paradigm shifts, etc etc but very underrated in the exam, lots of ppl gloss over this mod thinking its not important)
mod 2: research proposal (lit review time - i hated this, presentation of ur project (for us, it was in front of the principal + entire science department))
mod 3: statistical analysis (this mod was so ass but u have to pay attention SOOO closely, u miss a lesson and u feel like u wanna give up. there are so many analyses and tests and their conditions u have to memorise but if u spend time devising ways of memorisation u should be fine -- very important section in the hsc and esp ur trials)
mod 4: research report (hugest chunk, worth the most, takes up the most time, be smart with what u include in this report bc u get to use it in the hsc. so its smart if u include stuff from modules in here)
