I am new to preparation and one simiple question.
When was OG released and is it like it is released every year and is this valid only till dec 2010? If i give exam in Jan 2011 do I need to buy again the OG?
I believe it was released in 2009 and no they don't release an OG guide every year. From what I read, it will be another 2-3 years before another one is released.
