I wrote Dec 2012 and failed where i can find what is changed between dec’11 and May 12 exam ?
First of all Dec 2012 is yet to happen! Secondly, it’s never May 2012, it’s June 2012!!
Lastly, answering your question, lot has changed in Economics and some other LOS have been tampered with. Read the LOS and approach the topic.
Hope this helps.
