Hii

Registering over to Common Proficiency Course with Board of Studies of ICAI on or before June 30, 2017 is a must thing to be eligible for CA CPT 2018 December examination.

I am afraid to say that you can't apply for CA CPT 2018 December examination.

As per the officials, In case any candidate found in violation of CA CPT 2018 eligibility criteria, his/her candidature will be considered disqualified.

All the best.
