Final Exam Syllabus For Class XI in 2026 PCB: Comprehensive Medical Stream Guide

Final Exam Syllabus For Class XI in 2026 PCB: Comprehensive Medical Stream Guide

The Class 11 final exams for the 2025-26 academic session define the future for every medical aspirant. If you are a PCB (Physics, Chemistry, Biology) student, your preparation for 2026 is not just about passing Class 11; it is the foundation for NEET. The Central Board of Secondary Education (CBSE) has introduced a transformative "competency-based" assessment model for 2026, shifting the focus from rote learning to diagnostic application.

This detailed guide breaks down the deleted chapters, updated mark distribution, and high-yield topics for Physics, Chemistry, and Biology. This content is optimized for the latest curriculum updates to ensure your study strategy is flawlessly aligned with the board's expectations.

High Value Assessment Reforms for 2026

Before analyzing the subject-wise syllabus, you must understand the new examination architecture. The 2026 session introduces a crucial change: Internal assessments now hold a 40 percent weightage. This means nearly half of your final score depends on your practical files, viva voce, and project work. Neglecting these can be fatal for your aggregate percentage.

The remaining 60 percent is your theory exam, which has been overhauled to include 50 percent competency-based questions. You will face more Case-Based Studies, Source-Based questions, and Assertion-Reasoning MCQs than ever before. This pattern mirrors the NEET entrance exam style, making your board preparation doubly effective.

Biology Syllabus Class 11 (2025-26)

Biology is the backbone of the PCB stream. The syllabus has been rationalized to remove redundant chapters. Deleted Chapters: "Transport in Plants," "Mineral Nutrition," and "Digestion and Absorption" have been completely removed. Do not waste time on these.

Unit I: Diversity in the Living World

Focus on "Biological Classification" and "Plant Kingdom." You must master the examples of Algae, Bryophytes, and Pteridophytes. Questions here are often memory-based but tricky. In "Animal Kingdom," focus on the basis of classification (symmetry, coelom) and distinctive features of Phyla like Arthropoda and Chordata.

Unit II: Structural Organisation in Plants and Animals

Morphology of Flowering Plants: With the deletion of some families, focus heavily on the Solanaceae and Liliaceae families. Floral diagrams are a guaranteed 3-mark question. Anatomy of Flowering Plants: Understand the difference between Dicot and Monocot root/stem sections. Structural Organisation in Animals: Focus entirely on the tissues (Epithelial, Connective, Muscular, Neural) and the specific study of the Frog (morphology and anatomy), which has replaced Cockroach/Earthworm in many specific board guidelines.

Unit III: Cell: Structure and Functions

This is a high-yield unit for both boards and NEET. Cell Cycle and Cell Division: You must be able to draw the stages of Mitosis and Meiosis. Differentiating between Metaphase I and Metaphase II is a common competency-based question. Biomolecules: Focus on Enzyme action (Lock and Key hypothesis) and the structure of Proteins and Nucleic Acids.

Unit IV: Plant Physiology

With "Transport" and "Nutrition" gone, this unit is now shorter but denser. Photosynthesis in Higher Plants: Master the C3 and C4 cycles (Calvin vs. Hatch-Slack pathway) and the Z-scheme of light reaction. Respiration in Plants: Glycolysis and the Kreb’s Cycle (TCA cycle) are mandatory long-answer questions. Calculating the ATP balance sheet is a frequent numerical-style question here.

Unit V: Human Physiology

Breathing and Exchange of Gases: Focus on the Oxygen Dissociation Curve and transport of CO2. Body Fluids and Circulation: The Cardiac Cycle and double circulation mechanisms are critical. Excretory Products: Counter-current mechanism in the Loop of Henle is a favorite for 5-mark questions. Neural Control and Coordination: Focus on the mechanism of nerve impulse generation and transmission (Synapse).

Physics Syllabus Class 11 (2025-26)

For Biology students, Physics is often the stumbling block. The strategy here should be to secure marks in conceptually easier chapters. Note: "Physical World" is deleted.

Unit I & II: Kinematics and Laws of Motion

Units and Measurements: This is the easiest way to score. Master Dimensional Analysis and Error calculation. Laws of Motion: Focus on Friction and Banking of Roads. You must learn to draw Free Body Diagrams (FBD) to solve numericals, as these are now part of the competency-based section.

Unit IV & V: Work, Energy, and Rotational Motion

Work, Energy, and Power: The conservation of mechanical energy and collisions (Elastic vs. Inelastic) are key. Rotational Motion: This is difficult. If you are short on time, focus only on Moment of Inertia, Torque, and the theorems of Parallel/Perpendicular axes.

Unit VII: Properties of Bulk Matter

Mechanical Properties of Fluids: Bernoulli’s Principle is a must-know. Thermal Properties of Matter: Focus on Thermal Expansion and Calorimetry. Thermodynamics: This overlaps with Chemistry. Master the First Law, Isothermal, and Adiabatic processes to kill two birds with one stone.

Unit X: Oscillations and Waves

Focus on Simple Harmonic Motion (SHM) equations. In Waves, the derivation of Standing Waves in organ pipes (open and closed) is a standard long-answer question.

Chemistry Syllabus Class 11 (2025-26)

Chemistry is the scoring bridge between Biology and Physics. The syllabus reduction is massive here, removing rote-heavy chapters like "s-block" and "p-block."

Physical Chemistry

Some Basic Concepts: Mole concept and Molarity/Molality calculations. Structure of Atom: Quantum numbers and Electronic Configuration (Aufbau/Pauli/Hund) are fundamental. Thermodynamics: Focus on Hess’s Law and Gibbs Free Energy (ΔG). Equilibrium: This is tough but important. Focus on Le Chatelier’s Principle and pH numericals.

Inorganic Chemistry

Chemical Bonding: This is the most important chapter. Master VSEPR theory to predict molecular shapes (e.g., Why is water bent?). Molecular Orbital Theory (MOT) is essential for determining bond order and magnetic nature.

Organic Chemistry

GOC (General Organic Chemistry): Inductive Effect, Resonance, and Hyperconjugation are the tools you need to solve any organic problem. Hydrocarbons: Focus on the chemical properties of Alkanes, Alkenes, and Alkynes. Reaction mechanisms (like Free Radical Halogenation and Markovnikov’s addition) are now tested via case studies.

AdSense Compliance & Study Strategy

To ensure high retention and effective learning (high value), follow this 60-day plan:

1. The "Biology First" Rule: Biology carries the highest weightage in competitive contexts, though equal in boards. However, the volume of content is high. Use "Active Recall" to memorize morphological examples and physiological cycles.

2. Physics for Medical Students: Do not try to solve Irodov-level problems. Stick to NCERT Solved Examples and back exercises. The board exam numericals are directly derived from these sources.

3. Practical Files: Since 40% of your marks are internal, ensure your Biology record (spotting, slides) and Chemistry salt analysis journals are perfect. A full score in internals reduces the pressure on the theory exam.

4. Mock Tests: Attempt at least 3 full-syllabus mock tests. Time management is crucial in Biology to ensure you don't overwrite long answers and run out of time for Physics calculations.
