Conversion from old to new course

Guys I have skipped my CA final exam for Nov 19 (old course).Now I want to convert to new course for grp 2 only as I hv cleared my grp 1 already.So do I need to wait for the results as I had filled the exam for Nov 19 ,so until the results come out I will technically be an old course student..Is that the rule or I can convert before the result comes out?? Please help
