How to Study Class 12 Physics, Chemistry in 20 Days for Compartment Exam

Didn’t pass  CBSE Class 12 Physics or Chemistry on your first attempt? It’s okay—the compartment exam is your second chance, and 20 days are enough to make a strong comeback if you plan smartly.

Whether it’s weak concepts, missed topics, or exam pressure that holds you back, this guide will help you overcome those obstacles and focus on what matters most.

Let’s break down how to study Physics and Chemistry in 20 days effectively, with a clear strategy, day-wise plan, and practical tips.

20-Day Study Plan for Physics and Chemistry

Here’s a practical and easy-to-follow 20-day study plan designed to help you cover all the topics in Class 12 Physics and Chemistry for the 2025 compartment exam. Stick to this schedule with discipline and confidence to make the most of your time.

Physics Preparation (Days 3–8)

These six days are crucial to build a strong grip on important Physics concepts, formulas, and derivations. Focus on NCERT-based questions, revise key topics daily, and practice numericals to boost your accuracy and speed.

 Focus on These Topics:

• Current Electricity

• Ray Optics & Wave Optics

• Magnetic Effects of Current

• Dual Nature of Matter & Atoms

• Nuclei

• Communication Systems (easy and scoring)

 Tips to Study Physics:

• Most questions in the compartment exam are directly from NCERT.

• Practice derivations daily. Understand the logic, don’t just memorize.

• Make a formula sheet and revise it twice daily.

• Practice drawing and labeling neat diagrams.

• Solve 5–10 numericals per day from each chapter.

• Use CBSE Class 12th previous year papers and compartment-specific questions for practice.

Chemistry Preparation (Days 9–14)

These six days should be dedicated to mastering both Organic and Inorganic Chemistry, along with essential numericals from Physical Chemistry. Focus on NCERT, write and revise reactions, and practice past questions daily.

Focus on These Topics:

• Electrochemistry

• Chemical Kinetics

• p-Block and d-Block Elements

• Coordination Compounds

• Haloalkanes and Haloarenes

• Alcohols, Aldehydes, and Carboxylic Acids

• Biomolecules & Polymers (short and high scoring)

Tips to Study Chemistry:

• Read every line carefully—underline key definitions and reactions.

• Prepare a notebook for name reactions and conversions.

• Focus on mechanisms, IUPAC naming, and reaction conditions.

• Practice questions on molarity, rate law, and Nernst equation.

• Memorize group trends, structures, and reactions.

• Solve past Chemistry compartment papers to understand patterns.
