Overview

Class 10 Biology is among the most conceptually demanding subjects in the SSC Part 2 curriculum. The Punjab Curriculum and Textbook Board (PCTB / PECTAA) designs the official Biology textbook to build students' understanding of human body systems, genetic principles, biotechnology, and evolution - topics that matter both for board exams and for students who plan to continue into medical or biological sciences at the intermediate level.

The notes on this page are fully aligned with the PCTB syllabus for the 2026-2027 academic session. Each chapter is structured to cover key concepts first, followed by solved exercises, MCQs, short questions, and long questions. Whether a student is reviewing the Human Digestive System for a quick short answer or preparing a detailed response on Inheritance or Evolution, the chapter-wise format allows focused, efficient study rather than reading through the entire textbook each time.

These notes are SLO-based, meaning every topic maps to the Student Learning Outcomes defined by PCTB for this class. Students sitting for exams under Lahore Board, Rawalpindi Board, Gujranwala Board, Faisalabad Board, Multan Board, Sahiwal Board, Sargodha Board, Bahawalpur Board, or D.G. Khan Board will find this content directly relevant to their paper pattern, since all Punjab-affiliated boards follow the same PCTB-approved syllabus.

PDF versions are available for each chapter. Both English and Urdu medium editions are accessible from this page, making the notes practical for students across different school mediums. Teachers can also reference these materials when planning lessons or shortlisting important questions for class tests and board preparation exercises.
