Hello Aspirant

The eligibility criteria for the CEE exam is that the candidate must have passed their 12th Boards with 50% aggregate (for General Category students) or 45% (for SC/ST students). They must have passed all their exams from a UGC-Recognized Board of Examination.

Since you scored 27 in Math, this means you have failed in one subject and are thus, not eligible for the CEE exam.
