Do the past papers, the format rarely changes, know the formulae, national accounts, and all the components for aggregate demand,
know the interactions as wel, know the money market just as well as the goods market, know the tute questions inside out for each week, it does help, go through the lecture notes and if u dont understand everything, consult the textbook.
Dont break a sweat over it, if u do well, congrats, but crap, theres still a long way to go, everything is in the final, ECON110 has to be one of the most cumbersome readings ever.
