Question Paper Pattern (Theory)
As per the current TN 12th Physics pattern, the theory paper generally carries 70 marks and is divided into four parts with 38 questions in total. Students must answer questions from all four sections as per the internal choices given in the paper.
| Part | Type of questions | No. of questions / attempt rule | Marks pattern | Key points |
|---|---|---|---|---|
| Part I | Objective / MCQs | 15 compulsory questions | 1 mark each = 15 marks | Choose the correct option from four alternatives. |
| Part II | Very short answer | Around 9 questions; answer any 6 (one compulsory) | 2 marks each = 12 marks | Write brief, pointwise answers. |
| Part III | Short answer | Around 9 questions; answer any 6 (one compulsory) | 3 marks each = 18 marks | Derivations, problems and explanations. |
| Part IV | Long / essay answer | 5 compulsory questions | 5 marks each = 25 marks | Detailed answers with diagrams and formulae. |
The remaining marks to reach the overall 100 are covered by the internal/practical component, which is evaluated separately by the school and board.
