Hello friends, I registered in IPCC in January 2010 & now I'm revalidating my IPCC membership.I'm writing exams in coming november. I had three questions regarding it,

I did my ITT training in August 2010 & as my IPCC membership as ceased to be valid after more than 4 years ,is my ITT traing still valid or not? will I have to earn ITT certificate again?

can i appear in coming november examination after revalidation or I will have to wait for 8 months from now?

how many years of article training is required after completing both IPCC groups? is it 3 years or 3.5 ? 

thank you & please help me with these three questions. Regards!
