These are the 7 question papers PDFs hosted on icseboard.org for ICSE Class 10 Biology, organised by subject. Each section below explains what those papers cover before the download table.

This group has seven Biology (Science Paper 3) question papers from 2022 to 2026. The 2022 paper is a 40-mark First Comparative Examination, while the 2023 to 2026 papers are 80-mark exams. They cover the Class 10 syllabus, including cell division, genetics, and absorption by roots, with a compulsory Section A and a Section B with internal choice.

What the Biology Papers Cover Inside

Each paper tests the Class 10 Biology syllabus from the Selina textbook. The chapters include Cell, Structure of Chromosomes and Cell Division, Genetics, and Absorption by Roots. The questions ask you to name cell parts, explain processes, and solve genetics crosses.

Section A carries 40 marks. It starts with a 15-mark multiple-choice question. Section B has six questions, and you attempt any four. The mark tags in brackets, like [15] or [5], tell you how much each part is worth.

How to Use These Papers for Exam Preparation

Use these papers to check your preparation against the real exam format. The papers show you how CISCE frames questions around the same topics in different years.

• Start with the 2023 paper to learn the 80-mark pattern. Section A is compulsory, and Section B gives you choices.
• Time yourself for two hours. Use the first 15 minutes only to read the paper, as the instructions state.
• Check the mark tags in brackets. A 15-mark MCQ needs quick answers. A 5-mark question needs a labelled diagram and clear steps.
• Compare years to see which topics repeat. This tells you where to focus your revision.

You can find more study material on our main Class 10 page and the Class 10 books page. For official syllabus updates, visit CISCE.

Topics That Appear Across Years

The papers repeat questions from a few core chapters. The table below shows which topics come back year after year, based on the paper excerpts.

Genetics and absorption topics appear in three or more years. Give these chapters extra time when you revise.

Worked Example: Genetics Cross

Genetics questions appear in the 2023 and 2026 papers. The 2023 paper asks about the sex chromosome in a human ovum. The 2026 paper asks about genetic disorders like haemophilia and colour blindness. Here is a worked example for a monohybrid cross.

Question: A homozygous tall pea plant (TT) crosses with a homozygous short pea plant (tt). What is the genotype and phenotype of the F1 generation?

Step 1: Write the parent genotypes. The tall parent is TT. The short parent is tt.

Step 2: Find the gametes. The TT parent can only pass on the T allele. The tt parent can only pass on the t allele.

Step 3: Combine the gametes. All F1 offspring get one T and one t. So, the F1 genotype is Tt for every plant.

Step 4: State the phenotype. Since T (tall) is dominant over t (short), all F1 plants are tall. The phenotype ratio is 100% tall.

This is the kind of logic the 2026 paper tests when it asks you to pick the correct genetic disorders from a list.

Common Mistakes Students Make While Studying

Students lose marks on Biology papers for a few common reasons. These mistakes come from how the papers are structured and how the questions are worded.

• Confusing osmosis and diffusion: The 2024 paper asks about guttation and imbibition. Learn the exact definition of each process. Do not mix up water loss from leaves with water absorption by roots.
• Writing MCQ answers in full sentences: The instructions say, “Do not copy the questions, write the correct answer only.” Writing the full question wastes time.
• Skipping diagrams: A 5-mark answer in Section B usually needs a labelled diagram. The 2022 paper asks you to name parts of a cell. Without a diagram, you lose easy marks.
• Mixing up mitosis and meiosis: The 2022 paper asks about cell division at the shoot tip. The answer is mitosis. Meiosis is a reduction division for making gametes, not for growth.
• Forgetting the 15-minute reading rule: You cannot write during the first 15 minutes. Use this time to read Section B and decide which four questions you will attempt.

Marking Scheme Tips for Section A and B

The mark tags in the papers tell you how much detail to write. A mismatch between your answer length and the marks is a common way to lose time and points.
