hi,

tnea stands for tamil Nadu Engineering Admissions (TNEA) 2020, see tnea is not a examination, it is a counselling process to admission in engineering courses, colleges of tamil nadu, almost 500+ colleges participate in tnea counselling, tnea counselling is based on candidates 12th score, candidates from other region of india as well as tamil nadu may participate in this counselling process.

due to covid 19 pandemic the 12th exam has delayed also the tnea counselling, right now no information is available. I suggest you to follow careers360 website as well as official site to know about latest dates.
