u must be knowing an AS level paper 2 ,the theory paper
will hav two sections ... the first section usually doesnt hav macroeconomics nd its more simpler to answer
section B they give u options , nd more often then not they give a question on exchange rates...
maybe how the different types fo exchange rates are used ,how it affects an economy,how is it used during times if inflation etc...
usually u start my defining wat exhgane rate is nd try to to xplain wat the question asks nd dat happens only if u r good with exchange rates' topic...
but obviously bcoz section b gives u three questions to choose from .. u can always avoid exchange rates
