Practice practice and practice. I would suggest go with the
topical mastery before attempting other school's papers.
Topical mastery is a type of revision where you solely focus on
the topic that you're doing. Practice questions from the same topic
and try to master the art of recording the entries. Once you
understood the fundamental of that topic, you may now start to
proceed attempting questions from the same topic from other school
prelim paper.
I have one POA teacher that paistakingly compiled 10 prelim
papers from 10 school, and take her precious time
to catergorized all questions I.e. if we were told to
practice on Bank reconciliation, we will know which schoool and
which questions to look for in the stack of paper.
If you want to do well, you will need to attain mastery
at each topic before proceeding to the next.
