FRM Changes made from Nov 2012 to May 2013

[original post removed]

Actually, I have prepared using Nov 2012 material. However they have made some changes in all the four different topics. Out of which, Valuation and Risk models have concrete changes.

Please advise me, other changes like review of probabily and statistics has been expanded to four sub topics. And also they have pulled from new edition book.

Would it affect?

Thanks,
