What students should know about the TN State Board
A short overview of how the board works, so you know where your homework fits.
State syllabus and textbooks
The TN State Board follows the Tamil Nadu syllabus and its Samacheer Kalvi textbooks, so questions are based on your own textbook rather than NCERT.
Public exams in Class 10 and 12
The Class 10 (SSLC) and Class 12 (Higher Secondary) public exams are conducted by the Directorate of Government Examinations. The Class 11 public exam was cancelled from 2025-26.
Tamil and English
The state follows a two-language policy of Tamil and English, and students study in Tamil medium or English medium.
Term exams through the year
Schools hold terminal exams such as the quarterly and half-yearly exams, and Classes 1 to 8 follow automatic promotion.
Check the latest rules. Exam rules, schedules and pattern can change from year to year. For current information, use the official notices of the Tamil Nadu School Education Department and the Directorate of Government Examinations. StudyHelpAI is an independent study tool and is not affiliated with either.

Find the HCF of 252 and 105
- Divide the larger number by the smaller: 252 = 105 × 2 + 42. The remainder is 42, not 0, so continue.
- Divide 105 by 42: 105 = 42 × 2 + 21. The remainder is 21, so continue.
- Divide 42 by 21: 42 = 21 × 2 + 0. The remainder is now 0, so stop.
The divisor at the last step is 21, so HCF(252, 105) = 21. Check: 252 = 21 × 12 and 105 = 21 × 5, and 12 and 5 have no common factor other than 1.
State Coulomb's law and write it in vector form
The force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. It acts along the line joining the charges.
- In magnitude: F = k q₁q₂ / r², where k = 1/(4πε₀) ≈ 9 × 10⁹ N m² C⁻².
- In vector form, the force on charge q₂ due to q₁ is F₂₁ = k q₁q₂ r̂₁₂ / r², where r̂₁₂ is the unit vector from q₁ to q₂.
- The force is repulsive for like charges and attractive for unlike charges.
For q₁ = 2 μC and q₂ = 3 μC placed 0.1 m apart: F = 9 × 10⁹ × (2 × 10⁻⁶)(3 × 10⁻⁶) / (0.1)² = 5.4 N (repulsive).
Explain the causes of the First World War
- Alliance system. Europe was divided into rival groups, the Triple Alliance and the Triple Entente, so a local conflict could spread.
- Militarism. The major powers built up large armies and navies.
- Imperial rivalry. Powers competed for colonies and markets in Asia and Africa.
- Nationalism. Strong national feeling, especially in the Balkans, increased tension.
- Immediate cause. The assassination of Archduke Franz Ferdinand of Austria at Sarajevo on 28 June 1914.

How to write good answers in TN Board exams
Understanding the solution is step one. Showing it in the right form is step two. Use the AI answer as a model, then write your own.
| Subject | What a good answer includes |
|---|---|
| Maths | The formula or theorem, every step of working in order, and the final answer clearly marked. Check your answer where you can. |
| Physics and Chemistry | The law or definition, a neat labelled diagram where relevant, balanced equations, and numerical working with units. |
| Biology | Correct terms, a neat labelled diagram, and an explanation of function as well as structure. |
| Social Science | Point-wise answers with causes and effects, correct names and dates, and a map where the question asks for one. |
| Tamil | The meaning (பொருள்), the context and the key idea of the verse or passage, written in clear, correct Tamil. |
| English | The right format for the task (letter, essay, notice), clear structure, and careful grammar and spelling. |
These are rough guides. Marks depend on the question, the subject and the year, and examiners usually reward each correct point or step. Follow your teacher's guidance and practise with previous question papers and the sample papers released by the Directorate of Government Examinations.
Check the answer. StudyHelpAI is an AI tool and can occasionally make a mistake in a calculation, fact or step. Compare important answers with your Samacheer Kalvi textbook or ask your teacher before you rely on them.

Five habits that make the answers more useful and closer to what your exam needs.
Name your class and TN Board
Start with "Class 10 TN Board" or "Class 12 TN Board". The answer is then pitched at the right level for your syllabus instead of a general or CBSE answer.
Tamil medium students: ask in Tamil
Switch to தமிழ் and ask your question in Tamil to get the answer in Tamil. Check that the terms match the ones in your own textbook.
Practise for term exams
Before quarterly or half-yearly exams, ask for practice questions on a chapter and then try them yourself. It cannot know your exact paper, so use it for practice, not prediction.
Clear doubts when no teacher is around
If a doubt from tuition or school comes up in the evening, ask it straight away while it is fresh, then confirm the key point with your teacher the next day.
Snap a photo instead of retyping
For a textbook exercise or a question with a diagram, use the Image Upload tab, crop to just that question and send it.
