Well i think the strategy that you have given applies to all subjects in css, please can you tell which journals? of course you were not born with this economics knowledge you must have consulted some books from where you made your notes and MA economics is not a guarantee of securing good marks in economics, yes it adds to your knowledge but css is different. The way you have answered the query i doubt you have these unrealistic score of 150 in economics.
