Icwai revisionary question papers

Hai,

I  have registered for ICWA (inter)  under postal coaching scheme and received the study materials and question papers for revisionary test papers. My computer training is fixed in february 2013. I am planning to attend the examinations (both groups) in June 2013.  Now I want to know before which date i have to submit my revisionary question answers to the institute to attend the exams in June 2013.

An earlier advice is highly appreciated

Thanks....
