CUET Science Previous Year Question Papers (PYQs)

For aspirants aiming for top-tier science programs (B.Sc. Hons, B.Tech, or MBBS-alternative courses) in central universities like DU, BHU, or AMU, the CUET UG Science domain is a high-stakes arena. Unlike the NEET, which tests memory and speed across 180 questions, CUET requires a deep, application-based focus on the Class 12 NCERT syllabus.

Solving CUET Science PYQs with solutions allows candidates to:

• Master the Computer-Based Test (CBT) Interface: Get comfortable with the digital format and question navigation.

• Identify "Numerical vs. Theory" Balance: Recognize how the NTA balances conceptual Biology questions with calculation-heavy Physics and Chemistry tasks.

• Understand Case-Based MCQs: Learn to extract data from scientific passages, a unique feature of the CUET format.

• Analyze Syllabus Boundaries: Confirm that the exam stays strictly within the Class 12 NCERT, unlike NEET which often touches Class 11.

CUET Science Exam Pattern

Preparation starts with knowing the latest "All Compulsory" pattern for 2026:

Why Should You Solve CUET Science Question Papers?

Solving PYQs is the most effective way to transition from "Board Exam" thinking to "Competitive Exam" execution.

Mastering NCERT Application

CUET questions often use "Input Text" or diagrams to test if you can apply a formula in a real-world scenario.

• Biology: Tests your ability to interpret life cycles and ecological data.

• Physics: Focuses heavily on Electrostatics, Optics, and Modern Physics.

• Chemistry: Blends reaction mechanisms with solid-state and solution numericals.

Improving Precision under Pressure

With 50 questions in 60 minutes, you have roughly 72 seconds per question.

• Practice helps you identify "speed-breaker" numericals that should be tackled last.

• Reduces calculation errors in Chemistry (Solutions, Kinetics) and Physics (Current Electricity).

High-Weightage Topics from PYQs

Based on 2022–2025 trends, these units dominate the Science domain papers:

Biology

• Genetics and Evolution: ~12–15 questions. Focus on Mendelian patterns and Molecular basis.

• Reproduction: ~15 questions. High emphasis on Flowering Plants and Human Reproduction.

• Ecology: ~10 questions. Questions on Biodiversity and Environmental issues are common.

Physics

• Electrostatics & Current Electricity: ~12–14 questions. Practice circuit diagrams and capacitance.

• Optics (Ray & Wave): ~10 questions. Focus on lens formulas and interference patterns.

• Modern Physics: ~8 questions. Scoring area involving Atoms, Nuclei, and Dual Nature.

Chemistry

• Organic Chemistry: ~15–18 questions. Named reactions (Aldehydes, Ketones) and Biomolecules.

• Physical Chemistry: ~12 questions. Numerical focus on Electrochemistry and Chemical Kinetics.

• Inorganic Chemistry: ~10 questions. d-block and Coordination Compounds properties.

Subject-Wise Strategy for CUET Science PYQs

• Physics: Focus on "Formula Flashcards." PYQs often require you to recall a specific derivation-based result to solve an MCQ quickly.

• Chemistry: For Organic sections, solve PYQs by writing the mechanism once. For Physical, practice rounding off numbers to match the options without a calculator.

• Biology: Treat the NCERT as your Bible. PYQs show that even a single word change in an "Incorrect Statement" question can make a difference.

How to Use CUET Science PYQs Effectively

1. Timed Simulation: Always solve a full 50-question paper in a single 60-minute sitting to build "exam stamina."

2. Case-Study Focus: Dedicatedly practice the 1-2 case-based questions found in every PYQ set (usually 5 sub-questions each).

3. Active Review: After solving, don't just check the answer. Look at the explanation to see if there was a faster way to solve the numerical.

4. Error Tracking: Log whether a mistake was a "Conceptual Gap" (didn't know the topic) or a "Speed Trap" (misread the question under time pressure).
