Help me.

Hello Friends...

I m IPCC student. November 2010 was my first attempt in IPCC. Previously i had given many attempts in PE2. And i cleared 1st group of PE2. So i got exemption in A/c, audit and Law. And this time i had given Costing/fm, Infotech/sm, Incometax in IPCC. I m not sure to clear all the three subjects this time. But i m definitely sure that i would get exemption in Costing/FM Paper. So i need to appear in incometax and Infotech in May 2011. And my Final attempt is due on november 2012. So shuld i join the classes of Final from now or should i join after clearing these three subjects of IPCC in May 2011?? Plz give ur views...
