AP SSC Science Weightage 2026 Unit and Chapter-Wise Mark Distribution

AP SSC Science Weightage 2026: The subject includes two papers, Paper-I and Paper-II, totaling 100 marks. Both Paper I (Physical Science) and Paper-II (Biological Science) will be carrying 50 marks in the exam. AP SSC Physical Science contains 13 chapters. Among these, the maximum weightage carrying chapters are Carbon and Its Compounds, Light – Reflection & Refraction, The Human Eye and the Colourful World, with 11 marks, and Acids, Bases, and Salts with 10 marks. While some of the key chapters in Biology are Life Processes, How Do Organisms Reproduce, Heredity & Evolution, Control & Co-ordination, and Natural Resources. There are 10 chapters in Biological Science, including life processes, reproduction, coordination in life processes, heredity and evolution, environment, and so on. You can also check the detailed topics included these important chapters from AP SSC Science Syllabus 2025-26 .
In AP SSC Science Exam, both Physical and Biological sciences will consist of four sections, Objective type questions, very short answer questions, short answer questions, long answer questions with internal choices. AP SSC Science Paper I and Paper II will have 17 questions across 8 MCQs for 1 mark, 3 very short answer questions for 2 marks, 3 short answer questions for 4 marks, and 3 long answer questions for 8 marks. You will get 2 hours and 15 minutes to complete the entire AP SSC Science exam. Continue reading the article to know more on the AP SSC Science Weightage 2026 Unit and Chapter-Wise Mark Distribution.
