CUET Biology Syllabus 2026

All of the units that would be covered in the CUET Biology exam are defined and described in the CUET Biology syllabus 2026. The Common University Entrance Test (CUET 2026) is held for students seeking admission to Central Universities for undergraduate programmes. The CUET Exam Pattern is divided into three sections. Sections 1A and 1B include General and Special Languages, Section II – 27 Domain-specific Subjects, and Section III – General Test. Section II of the CUET  includes tests on all the domain-specific subjects. Section II includes the Biology domain. Biology question papers contain 50 questions, with all of them to be answered. The CUET Biology exam is of 250 marks.

CUET Biology Syllabus: Overview

The Biology CUET syllabus will be helpful to you if you’re looking for a career in B.Sc. in biology. Since biology is a conceptual and theoretical subject, you should make sure that all of your prior knowledge is accurate and up to par before starting the course. The following table includes the key details of the CUET Biology Exam and its Exam pattern.
