CBSE 12th Maths Student Reviews 2025

Here is the updated details of student reviews of CBSE Class 12 Maths paper:

• Many students felt that the paper was "Moderate" Level, but the linear Equations and calculus chapter questions were lengthy, and they took more time to complete.
• One student shared that she received Set 2, which had no direct questions. The entire question paper was based on Functions and Probability, with all the 5-mark questions being reduced to 2-3 marks, and some even to 1 mark.
• Another student thought, there were no questions from previous years' question papers or the CBSE sample papers. Despite integration being a high-priority topic, it only appeared in one question in Set 2.
• Students observed that, who received the Set 3 paper, it was very tough no direct differentiation nor direct integration and increasing decreasing was also very hard.
