Subject wise eligibility for converton to new scheme

 Dear friends,

                       I attemepted the CA Final exams. I had cleared my first group as well as got an exemption in second group(Indirect taxes). 

In lieu of mandatory convertion from old scheme to new scheme i need to convert to new scheme. My query is weather i can avail the exemption while writing second group in May 2011 or should i write all the four subjects. Any body who are aware of the same please forward the relevant announcements of the institue.

Thanking in advance in anticipation of reply.
