u can tell cos the BR and essay cover different topics. in the essay they gave us operations and finance so business report were marketing and HR. so you had to do marketing... but in one year a lot of people got confused so they were not penalised, might happen again but idk
honestly for trials, gatekeep LMAO apart from trusted close friends ofc ahaha
BUT when it comes to the actual HSC exam, share as much as you can bc unless ur rank 1st for everything you want to take home a good mark even if your rank is quite low + if your whole cohort does well then scaling...
