Mmm..
Whats the format of the exam? M/C, short answer and essay?
or M/C and essay?
last year, im sure we had short essay q's worth like 5-10 marks each, apart from our MCs'
if thats the case, then its yeah, 2-3 pages, with diagrams
in micro ALWAYS ALWAYS have diagrams when you are explaining things...suchas supply demand curves, price floor/ceiling, prisoner dillema matrix, deadweight loss etc etc
diagrams are your best friend, cause more often than not, you'll be asked to explain a specific concept, or use that concept and apply it in a practical situation
