dear yes its true do not prepare current affairs too early . wait until written result of 2012 is out that is the right time to prepare c.a . If u really want to do something then prepare topics like
Organizations ( SAARC, OIC , ASEAN, SCO and EU)
Pakistan relations till today at the end of year u will have updated data to insert in these topics
in addition geo strategic location of Pakistan , energy crisis( again dont remember figures now u should read this but insert updated data atleast of the end of this year )
there is alot of stuff to study but don't forget u have to update urself
