answer as many practice questions as possible just to give u an idea of what its like, it wont help in predicting what quesitons they'll ask but its important know the kind of vibe if u know what i mean (also ask people for feedback!!)
for creatives i recommend not have an incredibly convoluted plot line, keep the moment small but impactful, and try not to go overboard with dialogue/not introducing too many character etcs
for discursives you should aim to at least have a few real life examples within ur piece so it gives off the "exploring different perspectives" vibe like in the rubric, for example if im writing a discursive on like the power of art or some bullshit i could include a reference of that time banksy shredded his own artwork at an auction etc. etc.
