Series B
The Series B question paper carries the code 2005-B and follows a similar overall structure. It contains 40 numbered questions distributed across four sections, with a maximum of 80 marks and a duration of three hours.
Series C
Students looking for Series C should use the corresponding original question paper PDF when available. The series should be verified from the printed code on the first page before sharing or downloading it.
Important: The uploaded question paper copies available for this article establish the details of Series A and Series B. A separate Series C paper should be linked only after its availability and series code have been verified.
Section-Wise Pattern of the JKBOSE Class 10th Science Question Paper
The available Series A and Series B papers follow a four-section format. The sections include very short-answer questions, short-answer questions, questions carrying three marks and long-answer questions.
Section A: Very Short-Answer Questions
Section A contains Questions 1 to 18, with each question carrying one mark. This section tests students’ understanding of fundamental concepts from the Science syllabus.
The questions in the available papers include topics such as the refractive index of diamond, the blue colour of the sky, image formation by the human eye, magnetic effects, the general formula of alkynes, properties of metals, acids and bases, plant hormones, genetics and ecosystem processes.
The papers also include assertion-and-reason questions. Students are required to assess the statements and choose the appropriate answer according to the codes provided in the question paper.
Since each question carries one mark, students should pay attention to scientific terminology, formulas and basic conceptual understanding when practising similar questions.
Section B: Short-Answer Questions
Section B contains Questions 19 to 28, with each question carrying two marks.
This section includes questions requiring short explanations, definitions, distinctions and simple calculations. The available papers cover topics such as the power of a lens, electric charge, domestic electric circuits, displacement reactions, soaps and detergents, metals, autotrophs and heterotrophs, reflex action, reproduction and heredity.
Students should practise answering two-mark questions concisely while including the essential scientific points. Numerical questions should include the relevant formula, substitution and final answer with the correct unit.
Section C: Questions Carrying Three Marks
Section C contains Questions 29 to 37, with questions carrying three marks and internal choices in the available papers.
The questions cover a range of concepts from Physics, Chemistry and Biology. Examples include the power of accommodation of the eye, myopia, electric power and energy calculations, heating effects of electric current, magnetic field lines, chemical reactions, corrosion, minerals and ores, acids and alkalis, plant coordination, reproduction and ecological relationships.
Some questions provide an alternative through an “OR” option. Students should read both alternatives carefully and answer according to the instructions printed in the examination paper.
For three-mark questions, a well-organised answer with separate points, relevant examples and formulas where required can help students present their knowledge clearly.
Section D: Long-Answer Questions
Section D contains Questions 38 to 40, with each question carrying five marks in the available Series A and Series B papers.
This section requires more detailed explanations and may involve labelled diagrams, calculations or descriptions of scientific processes.
Topics appearing in the available papers include refraction of light, image formation by a convex lens, homologous series, the cleansing action of soaps, transport systems in plants and the structure and functioning of a nephron.
Students can use these questions to practise structuring longer answers. For diagram-based questions, labels should be clear and relevant. For numerical problems, the formula, calculation steps and final result should be presented in a logical order.
Important Topics Covered in the Science Question Paper
The available question papers include concepts from the major areas of the Class 10 Science curriculum. The following overview identifies topics appearing in the supplied Series A and Series B copies.
Physics
Physics-related questions include:
- Refraction of light and the laws of refraction.
- Refractive index and optical phenomena.
- The human eye, the retina and the power of accommodation.
- Myopia and its correction.
- Convex lenses and image formation.
- Electric current, potential difference and Ohm’s law.
- Electric power, energy consumption and heating effects of current.
- Magnetic fields, magnetic field lines and electromagnets.
- Overloading and short-circuiting in domestic circuits.
The papers include both conceptual questions and numerical problems. Students preparing for future examinations should practise calculations involving current, charge, resistance, power, energy and heat, alongside diagrams related to lenses and magnetic fields.
Chemistry
Chemistry-related questions include:
- The general formula of alkynes.
- Properties of metals, including malleability and ductility.
- Extraction of metals from ores.
- Acids, alkalis and the properties of acidic solutions.
- Chemical reactions and displacement reactions.
- Corrosion and its prevention.
- Minerals, ores and gangue.
- Exothermic and endothermic reactions.
- Rancidity and its prevention.
- Soaps, detergents and the cleansing action of soaps.
- Homologous series and organic chemistry.
Students should revise definitions, chemical equations, examples and differences between related concepts. Numerical and theoretical questions should be practised separately so that both calculation skills and conceptual clarity are developed.
Biology
Biology-related questions include:
- Excretion and the role of the kidneys.
- Plant hormones and chemical coordination in plants.
- Genetics and heredity.
- Autotrophs and heterotrophs.
- Reflex action and walking.
- Reproduction, gametogenesis and pollination.
- Regeneration and fragmentation.
- Transport systems in plants.
- The structure and functioning of a nephron.
- Food chains, trophic levels and ecosystem processes.
Students should focus on the functions of biological structures, differences between processes, labelled diagrams and explanations of important life processes. Practising answers in clearly separated points can make revision more effective.
What Should Students Do After the Examination?
After completing the JKBOSE Class 10th Science examination, students can use the question paper to review their attempt and identify areas that may need further attention.
1. Check the question paper series
First, confirm whether the examination paper was Series A, B or C. This helps students compare the correct set of questions and avoid confusion while discussing answers with classmates.
2. Review the questions attempted
Go through the questions in sequence and recall the answers written during the examination. Pay particular attention to numerical calculations, scientific definitions and questions involving diagrams.
3. Revisit difficult concepts
If a question was difficult, return to the relevant chapter and revise the underlying concept. Topics involving electricity, optics, chemical reactions, heredity and biological processes can be reviewed using textbook examples and practice questions.
4. Avoid relying only on unofficial answer keys
Students should be careful when comparing answers shared on social media or other unofficial platforms. An answer key circulated online may contain errors or may not correspond to the student’s question paper series.
The question paper itself can help students review what was asked, but the final evaluation will depend on the answers submitted and the applicable marking scheme.
5. Continue preparing for upcoming examinations
Students who still have examinations remaining should avoid spending too much time worrying about a completed paper. Reviewing mistakes can be useful, but preparation for the next subject should remain the priority.
