Expected Weightage

The Common University Entrance Test (CUET) for Biology, particularly the Biomolecules chapter, has shown specific trends in marking patterns and weightage over the last three years (2021-2023). Below is a detailed analysis:

1. Overall Weightage of Biomolecules in CUET Biology

• 2021-2023 Average: ~10-12% of the total Biology section.
• Total Questions (approx.): 4-6 questions (out of 50 in Biology).
• Marks Distribution: 16-24 marks (since each question carries 4-5 marks depending on the year).

2. Chapter-wise Breakdown (Biomolecules Subtopics)

The Biomolecules chapter is divided into key subtopics, and their weightage varies slightly each year:

3. Key Observations

• Carbohydrates Nucleic Acids have been consistently high-weightage topics.
• Proteins Enzymes saw a slight dip in 2023 but remain crucial.
• Lipids have a steady but lower weightage (~1 question per year).
• Metabolites Vitamins are occasionally tested (1 question in some years).

4. Marking Scheme Trends

• Correct Answer: +4 or +5 marks (varies yearly).
• Incorrect Answer: -1 mark (negative marking applied in all years).
• Unattempted: 0 marks.

5. Preparation Strategy

• Focus more on Carbohydrates, Nucleic Acids, and Proteins (cover ~70% of Biomolecules questions).
• Revise enzyme action, DNA structure, and lipid functions thoroughly.
• Practice NCERT diagrams and definitions (direct questions often asked).

Conclusion

Biomolecules is a moderately high-weightage chapter in CUET Biology, with Carbohydrates, Nucleic Acids, and Proteins being the most tested areas. A balanced preparation covering NCERT concepts and previous years’ trends will help maximize scores.
