Chapter-Wise Weightage for Mathematics

The AHSEC Class 12 Mathematics paper carries 100 marks, including 80 marks for theory and 20 marks for internal assessment. Students appearing for the compartment examination write only the 80-mark theory paper, as the internal assessment marks are carried forward.

• Calculus is the highest-weightage unit in the AHSEC Mathematics paper and contributes nearly half of the theory marks, making it the most important area for revision.
• Integration and Applications of Integrals together carry around 15 or more marks. Students should practise definite integration and area under curves thoroughly.
• Determinants and Matrices are important scoring units. Students should prepare row operations, adjoint and inverse of matrices, and solving systems of linear equations.
• Vectors and Three-Dimensional Geometry require regular practice of direction cosines, equations of planes, and the shortest distance between lines.
• Probability is a formula-based unit. Students should revise important concepts such as Bayes' Theorem and the Binomial Distribution, as questions from these topics are frequently asked in the examination.

Chapter-Wise Weightage for Physics

The AHSEC Class 12 Physics theory paper carries 70 marks, while the 30 marks for practical awarded in the main board examination are generally carried forward for students appearing in the compartment examination.

• Electrostatics and Optics together contribute around 22–23 marks, making them two of the highest-weightage units in the theory paper.
• Students should give priority to Gauss's Law, capacitor combinations, mirror and lens formulae, and the Young's Double Slit Experiment derivation, as these topics are frequently asked in the examination.
• Electromagnetic Induction and Alternating Current are also important scoring chapters. Students should practise transformer-based numericals, LCR circuits, and the important derivations from these units before the examination.

Chapter-Wise Weightage for Chemistry

The AHSEC Class 12 Chemistry theory paper carries 70 marks, while the 30 marks for practical obtained in the main board examination are generally carried forward for students appearing in the compartment examination.

• Organic Chemistry contributes a significant share of the theory paper, while Physical Chemistry includes several numerical-based questions that can be scoring with regular practice.
• Electrochemistry (around 9 marks) and Aldehydes, Ketones and Carboxylic Acids (around 8 marks) are among the highest-weightage chapters. Students should practise the Nernst equation, conductance numericals, and other important numerical problems regularly.
• In Organic Chemistry, students should revise important named reactions, including the Aldol and Cannizzaro reactions, as questions from these topics are asked frequently.
• Coordination Compounds and d- and f-Block Elements are also important scoring units. Students should prepare these chapters thoroughly, as the question pattern remains fairly consistent from year to year.

High-Scoring Topics and Preparation Strategy for Compartment Students

With limited days for revision, targeting the highest-weightage chapters across Mathematics, Physics and Chemistry gives you the maximum marks return for every hour of preparation. The table below identifies the three chapters in each subject that you should cover first.

Key preparation tips for AHSEC Compartment 2026:

• Previous Year Papers: Students should solve at least three years' AHSEC question papers, as the chapter-wise weightage and question pattern remain fairly consistent every year.
• NCERT Revision: Students should complete the NCERT Class 12 textbook examples and exercises before moving to additional practice, as many AHSEC questions are based on NCERT concepts.
• Physics Preparation: Students should regularly revise important derivations such as Gauss's Law, the Lens Maker's Equation/Mirror Formula, Young's Double Slit Experiment, and the Transformer Principle, as these topics are frequently asked in long-answer questions.
• Chemistry Revision: Students should thoroughly prepare important named reactions, including Aldol Condensation, Cannizzaro Reaction, Reimer-Tiemann Reaction, and Sandmeyer Reaction, as these questions appear regularly in the examination.
• Mathematics Practice: Students should write every calculation step while solving Mathematics questions, as marks are awarded for the correct method even if the final answer contains a calculation error.
