The CUET Mathematics 2025 exam was held from 13th May to 3rd June, and the question paper, answer key, and solution PDF are available for download here. The Mathematics paper in CUET evaluates a student's understanding of algebra, calculus, trigonometry, coordinate geometry, probability, statistics, and other core mathematical concepts.

As per the revised exam pattern, students had to attempt all 50 questions within 60 minutes, with the paper carrying a total of 250 marks. Each correct answer earns +5 marks, while every incorrect answer results in a –1 mark deduction.
