Ca-ipcc

I am planning to do CA-IPCC. I am a post graduate holding M.Com. Can you please clarify me on the following doubts.

1. I wish to write Group-1 exams in June 2016. Whether it is required to complete articleship before going for Group-1 exam.
2. Any age limit is there
3. Enrollment for CA-IPCC - any specific date for writing exams in Jun’16.
4. Any other formalities / conditions to be fulfilled in this regard.

Thanks in advance.

Regards,

MVN
