My only advice is study before you attend ground school! Try and learn everything they send you before ground school (I struggled with human factors & equipments I also until this day hate locations) we have one practical exam & two more final theory exams on both the A320 & A321! There's 3 different types of A320's and you'll need to know the different!
The process is defiantly worth it my first flight is a back of the clock flight to Perth!!! So exciting!
Defiantly watch out for debby she came to Melb for a week and taught us SOP's & Equipments/Location! She made most of us want to quit! She likes chocolate and she has this rule where if your phone rings you need to bring in lollies the next day HAHAHAHA just be really nice (she never smiles)
Ground school is the best I believe I'll still be friends with most once we graduate
