Branch-Wise Seats in TNEA 2026

CSE has the largest seat intake in TNEA 2026, driven by strong student demand and rapid seat expansion by self-financing colleges. New-age branches such as Artificial Intelligence and Data Science (AI and DS) and AI and Machine Learning (AIML) have seen a sharp rise in intake over the past three years. The table below shows approximate branch-wise seat distribution based on recent TNEA trends; the official 2026 figures are available on tneaonline.org.

The surge in CSE seats reflects statewide demand for software and technology roles. Students targeting CSE in top government colleges should note that seats there are limited and cutoffs are among the highest in TNEA; the bulk of CSE seats comes from self-financing colleges spread across Tamil Nadu districts.
