Listed below are some points that candidates preparing for the CUET 2026 Biology exam should keep in mind to attain a good score in CUET UG 2026 exam and get admission to the CUET participating college of their choice.
- Know the Syllabus and Exam Pattern: The first and foremost preparation strategy for any exam or subject is to know the exam pattern and syllabus. Once you do, deciding on the preparation strategy will be easier.
- Know the Important Chapters and Topics: Go through the CUET Previous Years’ Question Papers and CUET UG Exam Analysis to understand the question types, important topics, and topics with higher weightage. These will help you understand the difficulty level of CUET exam.
- Identify Strengths and Weaknesses: After completing the syllabus, identify your areas of strength and weakness. Based on that, decide which chapters to prepare thoroughly and which to leave out. Ideally, you should focus more on the areas of strength and leave out those in which you are not confident. However, before deciding on the topics to leave out, check the CUET Biology Chapter-wise weightage or importance of those areas. If your weak areas carry a high weightage, you must try to improve them. In case of a lower weightage, you can leave them and concentrate on preparing for the stronger areas.
- Practice and Solve Mock Tests and Question Papers: After completing the syllabus, the next step for CUET Biology preparation is to practice by taking regular CUET UG Mock Tests and solving the previous year’s question papers. Practice alone is not enough. After taking tests, get those analyzed by mentors or teachers to understand the areas of improvement and how to be more accurate and manage time more effectively.

NCERT is essential for CUET Biology preparation, but is not always sufficient. The NCERT books cover the fundamental concepts, forming the base of the CUET UG syllabus, but the exam often includes application-based questions that require deeper understanding of the topic. To maximize CUET score, candidates are advised to supplement NCERT with MCQ practice papers, previous years' qestion papers, and mock tests to improve speed and accuracy.
