Query regarding cs executive

Hi,
I am a Chartered Accountant, I have registered for CS executive in August 12, but could not give exam in December. Now m planning for June 13. I want to know how can i apply for exemption for IT training.
.
For exemption in IT Training you have to appear for "Online Exemption Test". You can register at https://icsi.sifyitest.com/ Registration and payment process is available therein.
.
Also want to know is it mandatory to write CC papers 
.
You have to write only One Response Sheet for each subject to be eligible for issue of Coaching Completion Certificate.

and by when I need to submit.

Last date for receipt of response sheets including resubmission in the Institute from the candidates who wish to be considered for enrolment for the examination to be held in June is 28 February & in December is 31st August.
