does this mean we need to extrapolate on the acronym of the RBA each time?
You don't need to do it for RBA as everyone knows that RBA = Reserve Bank of Australia.
But you will have to do it for say Aggregate Demand (AD), etc.
Are you sure we have to do it for every single response? My teachers always told me that you have to define it with the abbreviation once, then you can do it for the rest of the exam. It seems like a huge waste of time doing it for each response.
You will have to do it for every response. I agree it is a waste of time, but the few economics assessors I knew past and present all stated that you had to define and abbreviate for each response. But if you feel like not doing it that is on you.
Also, can we say like (X) in brackets when referring to ‘Exports’ or do we have to write the entire word out?
I agree with DoctorTwo's response on this, you should just write Exports instead of abbreviating it.
