Hello bhuvanesh
The eligibility criteria for the CCMT is the candidate should have passed and have secured atleast 6.5 CGPA or 60% aggregate marks ( GEN/EWS/OBC), whereas for SC/ST/pwd candidates it's 6.0 CGPA and 55% aggregate marks.
Therefore you are definitely eligible for the CCMT.
OGPA is nothing but overall grade point average.
I hope it helps
Best of luck.
