‍

The CBSE Class 12 Chemistry syllabus 2025-26 is structured to strengthen conceptual understanding while aligning with real-world applications. The NCERT textbook serves as the primary resource, covering the syllabus comprehensively, while reference books can aid in refining concepts. To excel in board exams, students should focus on understanding organic reaction mechanisms, practising numerical problems in physical chemistry, and revising important inorganic concepts regularly. A well-planned approach—consistent revision, problem-solving, and conceptual clarity—can make mastering Chemistry easier than expected.

CBSE Class 12 Chemistry Exam Pattern 2026

The CBSE Class 12 Chemistry exam for the academic year 2025-26 will follow the revised exam pattern. The pattern will include questions from all chapters, focusing on both understanding and application of key concepts.
