hi,

sorry to say diploma pass candidates are not eligible to participate in tnea counselling if candidates have not completed the HSC or 10+2 exam, tnea counselling is based on 10+2 score, 500+ engineering colleges participated in the exam , candidates from other state also participated in this counselling process.

candidate need to pass 10+2 course or equivalent  from a recognized education board with physics chemistry and mathematics as a subject.
