ICSE Class 10 Biology Practice Questions 2026: Since the Biology exam is in two days, students must focus more on revision rather than starting with new topics. Practice diagrams with explanations for important concepts. Solve sample papers to get insights into the difficulty level of questions asked over the years. Focus on time management while solving questions.
ICSE Class 10 Biology 2026: Unit-Wise Weightage
ICSE Biology paper 2026 will have two Sections, namely Section A and Section B. Both sections carry 40 marks each, making the total theory paper 80 marks. The remaining 20 marks are allotted for the internal assignment.
Given below is the unit-wise weightage for the Bio subject. Students must prioritize high-yielding topics over others.
Unit | Chapter Names | Section A Weightage (40 marks) | Section B Weightage (40 marks) | Total Weightage |
Unit 1: Basic Biology | Structure of Chromosomes, Cell Division | 2 | 9 | 11 marks |
Genetics | 2 | 11 | 13 marks | |
Absorption by Roots | 3 | 1 | 4 marks | |
Unit 2: Plant Physiology | Transpiration | 1 | 0 | 1 marks |
Photosynthesis | 3 | 10 | 13 marks | |
Chemical Co-ordination of Plants | 1 | 3 | 4 marks | |
Unit 3: Human Anatomy & Physiology | The Circulatory System | 3 | 5 | 8 marks |
The Excretory System | 5 | 0 | 5 marks | |
The Nervous System | 11 | 5 | 16 marks | |
Sense Organs | 5 | 4 | 9 marks | |
The Endocrine System | 2 | 0 | 2 marks | |
The Reproduction System | 2 | 6 | 8 marks | |
Unit 4 | Human Evolution | 1 | 5 | 6 marks |

Unit 6 | Pollution | 3 | 5 | 8 marks |
ICSE Class 10 Biology Paper 2026: Expert Tips
Here are some last-minute expert tips for students preparing for the Biology exam on March 13, 2026.
1. Practice neat labelled diagrams on key topics like Human heart, Neuron, Eye, Ear, Kidney & nephron, Leaf structure, etc. These are frequently asked in the exam and carry significant weightage.
2. Learn definitions and explanations on Human Anatomy, including Digestive system, Circulatory system, Excretory system, and Nervous system, among others.
3. Make short notes on key terms like Photosynthesis, Transpiration, Absorption by roots, Genetics & Evolution, Mendel’s experiments, Fertilization, and Pollination. Direct questions of 1-2 marks can be asked from these topics.
4. Practice reason-based questions, like Why are veins provided with valves? And why is transpiration important?
5. Make a small table for quick revision on the differences between Diffusion vs Osmosis
Mitosis vs Meiosis, and Pollination vs Fertilization.
6. Use the 15 minutes of reading time effectively. Read each question thoroughly and decide which question you want to attempt first. Attempt easy ones first and then proceed to the difficult questions.
