Exam eligibility of CA final

Dear all,

I cleared IPCC exam in May'10 and also joined my article ship on 16th August'10.

I have doubt about eligibility of CA final exam whether in May'13 or Nov'12.

Some of my friends are told me that your CA final exam in Nov'12 but others are told in May'13 after completing 2.5 years article ship period.

So, please told me whether i can appeared in the month of May'13 or Nov'12 and also provided specific notification issued by ICAI regarding that query.

Thanks in advance.
