CBSE Class 12 Chemistry Exam 2025: Paper Analysis & Student Feedback

The Central Board of Secondary Education (CBSE) conducted the Class 12 Chemistry examination on February 27, 2025, from 10:30 am to 1:30 pm. The paper, totaling 70 marks, was structured to assess students' conceptual understanding, problem-solving abilities, and application-based knowledge.

Exam Structure and Content

The question paper was divided into multiple sections:

• Section A: Multiple-choice questions (MCQs)
• Section B: Short-answer questions
• Section C: Long-answer questions
• Section D: Numerical and application-based questions

This balanced design ensured that students could demonstrate both theoretical knowledge and practical application skills. Notably, the exam adhered closely to the CBSE sample papers, with a significant emphasis on content from the NCERT textbook. Students who engaged in rigorous preparation using these resources found the exam largely manageable.

Student Reactions

Many students expressed that the paper was balanced and in line with their expectations. Organic Chemistry, often perceived as challenging, was straightforward in this exam. However, some students found the numerical problems in Physical Chemistry to be time-consuming and complex, requiring precise calculations. A few also noted that certain questions from Electrochemistry were trickier than anticipated.

Teacher and Expert Analysis

Educators observed that the paper was well-structured, aligning with the CBSE syllabus and emphasizing conceptual understanding over rote memorization. The inclusion of case-based questions effectively tested students' ability to apply theoretical knowledge to real-world scenarios. Assertion-reasoning questions were relatively simpler this year, allowing students to score easily. Overall, teachers agreed that students who had thoroughly studied the NCERT syllabus and practiced diligently found the paper approachable.

Challenges Faced

Despite the overall positive feedback, the paper presented certain challenges. Physical Chemistry numericals were particularly lengthy and complex, demanding significant time and effort. Some students felt that these questions were more suited to competitive exams like JEE rather than a board-level assessment. Additionally, the detailed nature of short-answer questions led to mental fatigue for some students by the time they reached the long-answer section.
