Not all of these have been asked yet I believe but these are most of the options:
Essay
Report
Speech
Feature Article
Letter
TV interview
Radio Interview
Brochure/Pamphlet(I have my doubts they'd actually do this but meh)
It also may be vaguely possible that you may have to write in the role of a character or write their journal entries(again, I have doubts they'd do it...)
I think thats most of them but as I said above, I have my doubts that you'd be asked to write the last one since that goes more in to the realm of Extension and I've only ever seen the brochure used in something related to Journeys.
