ਕੀ ਤੁਸੀਂ PSEB ਜਮਾਤ 10ਵੀਂ ਦੀ ਸਾਇੰਸ ਪ੍ਰੀਖਿਆ ਦੀ ਤਿਆਰੀ ਕਰ ਰਹੇ ਹੋ? ਚਾਹੇ ਤੁਸੀਂ ਆਪਣਾ ਹਾਲੀਆ ਪ੍ਰਦਰਸ਼ਨ ਵਿਸ਼ਲੇਸ਼ਣ ਕਰ ਰਹੇ ਹੋ ਜਾਂ ਅਗਲੀ ਪ੍ਰੀਖਿਆ ਲਈ ਤਿਆਰੀ ਕਰ ਰਹੇ ਹੋ, ਬੋਰਡ ਦੇ ਪ੍ਰਸ਼ਨ ਪੱਤਰ ਦਾ ਸਹੀ ਪੈਟਰਨ ਸਮਝਣਾ ਤੁਹਾਡਾ ਸਭ ਤੋਂ ਵੱਡਾ ਹਥਿਆਰ ਹੈ।
In this post, we provide a complete deep-dive analysis of the PSEB Previous Year Question Paper Class 10 Science . We have compared Set A, Set B, and Set C to reveal a surprising fact that every student needs to know.
LATEST PSEB Class 10th science Exam Structure Blueprint (2025-26 Pattern)
Based on the actual paper and the official structure PDF, here is the final paper pattern:
- Total Marks: 80 (Theory) + 20 (Internal Assessment) = 100
- Time: 3 Hours
- Total Questions: 28
| Section | Question Type | No. of Questions | Marks Per Q | Total Marks |
| Part A | Objective Type • MCQs (1-20) • Matching (21-25) | 25 | 1 | 25 |
| Part B | Short Answer (Attempt any 11 out of 15) | 11 | 2 | 22 |
| Part C | Medium Answer (Attempt any 6 out of 9) | 6 | 3 | 18 |
| Part D | Long Answer (Internal Choice available) | 3 | 5 | 15 |
| TOTAL | 28 | 80 |
🛑 The Big Reveal: Set A vs. Set B vs. Set C
Many students panic thinking they received a “harder” set than their friends. After analyzing the official 2025 papers (Code 05/A, 05/B, 05/C), here is the truth:
All three sets contain the EXACT same questions.
The only difference is the shuffling (ordering) of the questions.
- Example 1: The 5-mark question “Write five changes seen in girls at the time of puberty” appears as Q26 in Set A and Set B, but as an internal choice in Set C.
- Example 2: The numerical problem on a convex mirror ($u = -10$ cm, $f = 15$ cm) appears as Q17 in Set A, Q24 in Set B, and Q20 in Set C.
Conclusion: If you solve just one set completely, you have effectively prepared for all of them!
📊 Chapter-Wise Marks Weightage (2025 Pattern)
We have broken down the 80 Marks to show you exactly which units carry the most weight. Use this table to prioritize your revision.
| Unit Name | Weightage | Key Question Types |
| Metals & Non-Metals | 8 Marks | • 5-Mark Long Answer (Differences) • 2-Mark Reasoning • 1-Mark MCQ |
| Electricity | 8 Marks | • 3 or 5-Mark Numerical (Series/Parallel) • 1-Mark Formula/Unit |
| How Organisms Reproduce | 8 Marks | • 5-Mark Long Answer (Contraception/Puberty) • 1-Mark MCQ (Regeneration) |
| Light (Reflection/Refraction) | 7 Marks | • 3-Mark Numerical (Mirror Formula) • 2-Mark Conceptual (Refraction) |
| Life Processes | 7 Marks | • 3-Mark Diagram (Neuron/Nephron) • 2-Mark Short Answer (Stomach acid/Lungs) |
| Chemical Reactions | 6 Marks | • 3-Mark Reaction Balancing • 2-Mark Observation (Iron nail in CuSO₄) |
| Control & Coordination | 6 Marks | • 3-Mark Short Note (Plant Hormones) • 3-Mark Diagram (Neuron) |
| Human Eye | 6 Marks | • 3-Mark Reasoning (Rainbow/Hypermetropia) • 2-Mark Reasoning (Sky color) |
🎯 The “Must-Do” Questions (Guaranteed Scoring)
If you want to ensure you pass with good marks (90%+), master these specific questions that appeared in the 2025 paper. These patterns are highly repetitive.
1. The 5-Mark Section (Section D)
This section is extremely predictable. You must prepare these three topics:
- Biology: “Write methods of Contraception” OR “Write changes in girls at Puberty“.
- Chemistry: “Differentiate between Metals and Non-metals based on physical and chemical properties”.
- Physics: “Factors affecting Resistance of a conductor” OR “Why Copper/Aluminium are used for transmission”.
2. The Numerical Section (Part C)
- Light: A standard mirror formula problem. Example: An object is placed at 10 cm from a convex mirror of focal length 15 cm. Find position and nature.
- Electricity: Calculating total resistance or current in a circuit.
3. Important Diagrams (3 Marks Each)
Make sure you can draw and label these neatly:
- Neuron (Nerve Cell) – Asked in Q17 (Set B)
- Structure of Human Eye (Defects like Hypermetropia)
- Electron Dot Structure (e.g., Oxygen $O_2$)
🚀 Exam Strategy: How to Attempt the Paper
Based on the 2025 paper structure, here is the best strategy to maximize your score:
- Start with Part D (5-Mark Questions):
These 3 questions carry 15 marks and are direct textbook questions. Write point-wise answers (e.g., 5 points for changes at puberty). - Move to Part C (3-Mark Questions):
Focus on the Diagrams and Numericals here. Diagrams take less time and score full marks if labeled correctly. - Handle Part A (1-Mark Questions) Carefully:
Do not rush the MCQs.
- Tip: In Q1, remember that the filtration unit of the kidney is the Nephron.
- Tip: The image formed by a concave mirror when the object is at infinity is Highly Diminished.
