PCC Query

Dear All,

I joined my articleship in Dec 2006 & will be completing in June 2010.

I have cleared one Group in PCC & have given the other group ?

Is there any restriction on the number of attempts for writing my pcc exams ?

If i donot complete within the said attempt, will i have to do my articleship for the entire 3.5 years again or the one done earlier will hold enough?

please Guide.
