Let’s start with Physics. For your kind information, the time period is 3 hours only.
Physics Marking Scheme Class 12 NEB
| Chapter | MCQ(Multiple Choice Questions) | S.Q(Short question) | L.Q(Long Question) | Mark |
| Mechanics | 3 | 2 | 0 | 13 |
| Heat and Thermodynamics | 2 | 1 | 0 | 7 |
| Wave and Optics | 2 | 1 | 1 | 15 |
| Electricity and magnetism | 3 | 2 | 1 | 21 |
| Modern Physics | 1 | 2 | 1 | 19 |
- Note:-
- 15% is remembering/knowledgeable.
- 25% is understandable.
- 30% is related to formulas.
- 30% is a higher ability.
| Category | S.Q | L.Q | MCQ’s | Total items | Mark |

Note:- For 1 MCQ question you got 1 mark each also for 1 S.Q you got 5 marks each and for 1 L.Q you got 8 marks each.
In Group “A” there comes a total of 11 questions and question no. 1 comes on the base of knowledge likewise others.
In Group “B” there comes a total of 8 questions and question no. 1 comes on the base of knowledge and understanding(i.e. one question of 1 mark come from knowledge and Two questions of 2 mark come from understanding) likewise others.
