CUET Biology Syllabus 2025 For PCB Students: Download Syllabus PDF

The National Testing Agency (NTA) has released the CUET UG 2025 Biology syllabus, which is now available for candidates to download from the official CUET website at nta.ac.in. This syllabus is an essential guide for students aiming to excel in the Biology section of the Common University Entrance Test (CUET) and pursue undergraduate programs in this field.

To prepare effectively, it’s crucial for CUET aspirants focusing on Biology to thoroughly review the syllabus before diving into their study plans. The syllabus provides a comprehensive overview of all the topics that will be tested in the CUET Biology exam, making it the cornerstone of your preparation strategy.

The CUET is designed for students seeking admission to undergraduate programs at Central Universities. It has three sections:

1. Section 1A and 1B: Cover general and specialized language tests.
2. Section II: Focuses on 27 domain-specific subjects, including Biology.
3. Section III: A general aptitude test.

For candidates choosing Biology under Section II, the exam consists of 45-50 questions, of which they need to answer 35-40. The test carries a total of 200 marks. To ace this section, understanding the syllabus in detail is key to identifying and targeting the most important topics.
