C c papers are compulsory for inter group 1?

you are expected to complete the test papers and send the same before the due date. If you are a first class graduate, there are relaxations available. I don't think your registration will be cancelled; you probably can't appear for the examinations without submitting the test papers.

All the Best !

@ prajakta, don't worry, if you dont send test papers, your regn will not get cancelled..,

i suggest you to clarify with your RC, abt sending answer sheets.. as it differs from one RC and the other..
