Are we allowed to give extra information in brackets (like so) or is that something I should seek to avoid??
If it
adds substance to your response then yes, assessors for example want for a high court case, the section of the consitiuton, the name in that section that allows them to govern (external affairs) and the act that was implemented and is being disputed and then the end result with the effect on the DOP
so for example if saying it is apart of section 51 doesn't fit well with the flow but you could add it in brackets then sure or saying something like their are 39 Heads of power which the government can govern within will contextualise your response better or prove further knowledge then again do it
Don't include it if your going on a tangent that adds nothing to the response (1-4 markers), due to 7-10 markers being globally marked having the brackets and proving further knowledge becomes more important if it doesn't fit within your response
