old scheme to new scheme..exemption in a subject

iam in ca final old syllabus...cleared first group and will be attempting the november 2010 exam(old syllabus only)...since next attempt is the last attempt for old syllabus students and if still we dont clear also its mandatory to convert into the new scheme right...so my doubt is..if i get an exemption in any subject in the coming november exam but dint pass the group...am i supposed to write that subject also after getting converted into new scheme??
