I kept my preparation very limited as I have a strong Accounting Background:

I analyzed 10 years past papers and earmarked important topics. Revised them in a day and went for the paper.

However, I will suggest you to analyze past papers and earmark important topics, then attempt at least 10 questions of each topic from past papers. If you can attempt these questions correctly, you are good to go.

For MCQs, once again, take 10 year past papers and solve all of them.
