Past Paper Analysis 2025 — Which Topics Repeated Most in 9th and 10th Class Exams?

Past Paper Analysis 2025 — Key Insights for 2026 Exam Preparation

If you want to score high in 2026 board exams, studying the patterns from 2025 papers is one of the most efficient strategies. Here is a subject-by-subject analysis of what appeared most frequently across major BISE boards in 2025.

Disclaimer: This analysis is based on papers from BISE Lahore, BISE Multan, BISE Faisalabad, and BISE Karachi. Individual board papers may vary slightly.

10th Class Physics — Most Repeated Topics 2025

Physics 10th class papers in 2025 showed strong patterns in the following areas:

High-Frequency Topics (Appeared in 3+ Board Papers)

• Simple Harmonic Motion (SHM) — definition, examples, and conditions
• Ohm's Law and Resistance — numerical problems
• Lenz's Law and Electromagnetic Induction — theoretical + numerical
• Lenses (Convex/Concave) — ray diagrams and focal length problems
• Radioactivity — types of radiation, half-life, nuclear reactions

Long Questions That Repeated

• Explain the principle and working of a transformer
• Derive the lens formula and solve numerical
• Explain radioactive decay with examples

Tip for 2026: Focus on the five high-frequency topics above. Practice at least 3 numerical problems from each.

10th Class Chemistry — Most Repeated Topics 2025

High-Frequency Topics

• Organic Chemistry — hydrocarbons, functional groups, reactions
• Acids, Bases and Salts — neutralization reactions, pH, buffer solutions
• Chemical Equilibrium — Le Chatelier's principle, equilibrium constant
• Environmental Chemistry — air and water pollution, ozone layer
• Electrochemistry — electrolysis, galvanic cells, Faraday's laws

Long Questions That Repeated

• Describe the industrial preparation of Sulphuric Acid (Contact Process)
• Explain the types of hydrocarbons with examples and structural formulas
• What is electrolysis? Explain with the electrolysis of water

Tip for 2026: Organic Chemistry long questions are almost certain to appear. Master them.

10th Class Biology — Most Repeated Topics 2025

High-Frequency Topics

• Homeostasis — thermoregulation, osmoregulation, excretion
• Coordination and Control — nervous system, hormones, sense organs
• Reproduction — sexual and asexual, plant and animal reproduction
• Genetics — Mendelian inheritance, monohybrid/dihybrid crosses
• Biotechnology — genetic engineering, cloning, applications

Diagram Questions That Appeared Often

• Human kidney — labeled diagram + function
• Human brain — labeled diagram
• Plant reproduction cycle

Tip for 2026: Biology diagrams are worth 5–8 marks per question. Practice drawing labeled diagrams for all major organ systems.

10th Class Mathematics — Most Repeated Topics 2025

Mathematics is the most predictable subject — the same types of problems appear every year.

Must-Know Topics

• Quadratic Equations — factorization, quadratic formula, applications
• Matrices — types, operations, determinants, inverse matrices
• Trigonometry — identities, solving triangles, heights and distances
• Geometry — theorems on circles, tangents, chords
• Statistics — mean, median, mode, standard deviation, frequency distributions

High-Marks Numericals (Almost Always Appear)

• Matrix multiplication and finding inverse
• Solving quadratic equations by all three methods
• Proving trigonometric identities
• Calculating standard deviation from ungrouped data

Tip for 2026: Show all working steps even if the final answer is wrong. Examiners award partial marks for correct method.

9th Class Analysis 2025

9th Physics — Frequent Topics

• Kinematics — equations of motion, graphs, free fall
• Force and Newton's Laws — application problems
• Work, Power, Energy — numerical problems
• Properties of Matter — density, pressure, Archimedes' principle

9th Chemistry — Frequent Topics

• Atomic Structure — Bohr's model, electronic configuration
• Periodic Table — trends, groups, periods
• Chemical Bonding — ionic, covalent, metallic bonds
• Electrochemistry — introduction, basics

9th Biology — Frequent Topics

• The Cell — structure, organelles, functions
• Nutrition — types, human digestive system
• Transport — blood, heart, circulatory system
• Respiration — aerobic, anaerobic, breathing mechanism

How to Use This Analysis for 2026 Preparation

1. Make a checklist of all high-frequency topics from each subject
2. Study those topics first and study them deeply
3. Collect 2024 and 2025 past papers from your BISE board specifically
4. Solve past papers under timed conditions
5. Do not ignore low-frequency topics completely — cover them at a surface level so you are not caught off guard

A Word of Caution

Past paper analysis helps you prioritize — it does not guarantee what will appear. Board examiners sometimes introduce new types of questions or shift focus to chapters that previously appeared less frequently.

The safest strategy: Master high-frequency topics thoroughly, and review low-frequency topics at least once.

Good preparation beats prediction every time.
