No entrance exam. Admission to every government, government-aided, and self-financing engineering college in Tamil Nadu runs purely on Class 12 board marks.
TNEA is managed by Anna University and is the most relevant admission process for the majority of Tamil Nadu engineering students — it covers everything except NITs, IITs, IIITs, and GFTIs, which use JoSAA instead.

Correct — TNEA is unique among the exams in this hub because admission runs purely on your Class 12 Physics, Chemistry, and Mathematics marks, using the cutoff formula. There's no separate test to prepare for; your board exam performance is the entire admissions criterion.
Every registered student gets a random number assigned at registration, used purely to break ties when two students have identical cutoff marks. Registering early (as soon as the portal opens) gets you a lower random number, which is advantageous in ties — a student with cutoff 198.5 and random number 1,024 gets priority over one with the same cutoff and random number 98,342.
A counsellor can project your realistic college range early, not after results.
