Query on balance period of articleship after termination

Dear Experts,

I had completed my articleship for 11 months ( 20th Dec 2014 - 20th Nov 2015 ) and then i took termination as i was waiting for my IPCC results (being from Direct Entry Mode).

My query is now that i am joining a new firm from 21st March 2016,

what shall be the balance period to be written on FORM 102 & 103 so that there is no shortage in my total 3 years articleship period served ?

21st March 2016 - 21st April 2018 (balance 25 months) ???

Also, in which attempt can i give my ca finals ??

Thank you for all your help
