Ca articleship to do while working

Hi friends,

I would like to get guidance from you on my below query,

I have cleared my CA Inter group 1 in 2007 May and got in to job(have passed B com in 2005). And in the year 2012 I have cleared 2nd group of Inter and got cource certificate too.

 As I didn't finished articleship training, I could'nt write the final exam.

Now I am working in an MNC KPO in Chennai, previous worked in audit firm for one year(pre qualifying the Inter 1st group)

 My question is how can I get eligible to write the Final examinaion ? please reply !
