PSEB Class 11 Biology Syllabus 2023-24: Download New Curriculum in PDF Here

PSEB Class 11 Biology Syllabus 2023-24: The Punjab School Education Board (PSEB) has released the subject-wise syllabus for Class 11 for the current academic session. The Board has developed the class 11 syllabus with the intention of providing a comprehensive and structured educational experience for students. It aims to equip them with the necessary knowledge, skills, and competencies to succeed academically and in their future endeavours. Hence, to get the best results, students must be thorough with their new syllabus. In this article, we have provided the new syllabus of Class 11 Biology in which you will get the detailed list of topics to be prepared in each chapter of Biology. It also mentions the weightage assigned to each unit for the 2023-24 assessment. Additionally, students will also get to know the details of practical and internal assessment along with the design of question paper for PSEB Class 11 Biology Exam 2023-24.
