TNEA cut-off: how it is calculated and what to revise
Tamil Nadu Engineering Admissions
TNEA has no entrance exam: your engineering cut-off comes from your Class 12 marks. The general formula is Mathematics + Physics ÷ 2 + Chemistry ÷ 2, out of 200. So Mathematics counts for 100, Physics for 50 and Chemistry for 50. A normalisation step is applied across boards.

How the cut-off decides your seat
Your cut-off, out of 200, ranks you for counselling. Mathematics is worth twice as much as Physics or Chemistry in the formula, so one extra mark in Maths is worth two in either of the others. Marks from different boards go through a normalisation process; the official notice explains how.
What the formula means for you
- One mark in Mathematics adds 1 to your cut-off; one mark in Physics or Chemistry adds 0.5.
- There is no entrance paper to prepare, so your Class 12 theory papers are the whole game.
- Revise the highest-weight Class 12 units in all three subjects and write answers the way the board expects.
- Keep your final board papers for Maths first on your revision plan.
Concepts to revise first
Each is a one-minute animated lesson, in English and Hindi, with the exam-style answer written out. They cover the Class 11 and 12 ideas this route tests; CogniGuru does not have TNEA-specific question banks.
Physics
- Projectile Motion — why 30° and 60° land at the same spot
- Work, Energy, Power — why pushing a wall does zero work
- Why is the work done by centripetal force zero? — Class 11
- Torque vs Force — why pulling at an angle feels weaker
- Moment of Inertia — why a ring is harder to spin than a disc
- Simple Harmonic Motion vs Periodic Motion — why 'it repeats' isn't the test
- Electric Field vs Electric Potential — the vector and the scalar
- Why can electric field lines never cross? — Class 12
Chemistry
- Mole vs Molar Mass vs Avogadro's Number — Class 9
- Orbit vs Orbital — Class 11
- How to find sp, sp² or sp³ hybridisation — Class 11
- Electronegativity vs Electron Affinity — Class 11
- Le Chatelier's Principle Explained — Class 11
- Galvanic vs Electrolytic Cell — Class 12
- Molarity vs Molality vs Normality — does heating a solution change its concentration?
- Periodic Trends — why potassium is BIGGER than sodium despite more protons
Mathematics
- Function vs Relation — Class 11
- One-one vs Onto Functions — Class 12
- Domain vs Range — why one value can quietly break a function
- Definite vs Indefinite Integral — Class 12
- Differentiation vs Integration — two questions about the same curve
- Dot Product vs Cross Product — Class 12
- What is conditional probability? P(A|B) explained — Class 12
- Permutations vs Combinations — the one question that decides which formula to use

Common questions
- Is there an entrance exam for TNEA?
- No. Admission is based on your Class 12 marks in Mathematics, Physics and Chemistry.
- How is the TNEA cut-off calculated?
- Cut-off = Mathematics + Physics ÷ 2 + Chemistry ÷ 2, with each subject taken out of 100, so the maximum is 200. For example 95, 92 and 90 give 95 + 46 + 45 = 186.
- Does normalisation change my cut-off?
- A normalisation process is applied so that marks from different boards can be compared fairly. Read the official TNEA notice for how it works in your year.
- Will CogniGuru give me TNEA mock papers?
- Not yet. CogniGuru explains the Class 11 and 12 concepts that TNEA tests, one minute at a time, with the exam-style answer written out. It does not have TNEA question banks or mock tests, so use the official previous papers for practice.
