Hey, I think this is the first year they making ECON1203 have a mid sem. It use to be two mini quizes like ECON1101. Basically ECON1203 and ECON1101 swapped assessment structures haha. Since there is a change, it is unlikely any past papers are around. There are final exam papers for ECON1203 though, although they focus more on the 2nd half of course.
ACCT1501 does not have past papers as they do not let students keep the papers. It just usually gives you transactions and ask you to write journal entries. You also need to know how to do adjusting entries e.g. writing off Allowance for Doubtful Debts. Then you need to be able to apply those transactions into either Income Statement and/or Balance Sheet.
