Direct entry scheme

I have completed my ITT and OT in the month of july'14 but started my articleship on 11th august'14. So I won't be eligible for IPCC exams in May'15 but will be for Nov'15. I wanted to ask:
.
1. Will the excess months i.e. excessive of 9months be counted in the those 3 years of articleship?

Yes, because after 9 months student meets the eligibility criteria and not a cut-off point.
.
2. When will I eligible for CA final exam? After completing 2.5 years or 3 years of articleship?

2.5 years (i.e. last six months of training including excess leave, if any.)
