CUET 2026 Unit-Wise Biology Syllabus
Before starting CUET 2026 preparation, students must go through the latest CUET syllabus for Biology. It includes all the important topics and chapters that will be covered in the exam. The syllabus is divided into units, and each unit has specific subtopics. Knowing the complete and updated syllabus helps students focus on what matters most and plan their studies better. This way, they can manage their time well and avoid missing any key topics. Staying aware of the latest syllabus changes is important to boost preparation, stay confident, and score higher in the CUET Biology section.

CUET Biology 2026: Exam Pattern
The CUET Biology exam is simple. It has multiple-choice questions (MCQs) with four options, and you choose the correct one. The questions come from your high school biology topics, like cell biology, genetics, ecology, and more. The exam may have different sections and cover the main ideas of biology. The number of questions and time limit can change, so check the details for your year. The test checks how well you understand biology and how you can use what you’ve learned.
