How to Ace Physics in CBSE Class 12 Board Exams?

 

Physics is a subject that demands a lot of attention and effort from the students of CBSE Class 12. It involves a deep understanding of concepts, formulas, derivations, and numerical problems. However, with proper planning, practice, and revision, you can excel in physics and enhance your overall percentage. In this blog post, we will share some tips and strategies to help you prepare for physics in CBSE Class 12 board exams.

1. Know the syllabus and weightage of each unit The first step to prepare for physics is to know the syllabus and the weightage of each unit. The CBSE Class 12 Physics syllabus is divided into 10 units, as shown in the table below:

Unit No.         Name of Unit	Marks
Unit–I            Electrostatics	15
Unit-II            Current Electricity
Unit-III           Magnetic Effects of Current and Magnetism	16
Unit-IV           Electromagnetic Induction and Alternating Currents
Unit–V           Electromagnetic Waves	17
Unit–VI          Optics
Unit–VII         Dual Nature of Radiation and Matter	10
Unit–VIII        Atoms and Nuclei
Unit–IX          Electronic Devices	12
Unit–X            Communication Systems
Total	70

You should allocate more time and attention to the units that carry more marks, such as electrostatics, electromagnetic waves, and optics. You should also cover the topics that have been deleted by the board due to the Covid-19 pandemic. You can find the updated syllabus and the list of deleted topics on the official website of CBSE.

2. Read the NCERT textbook and make notes:

   The NCERT textbook is the best source of study material for physics, as it covers the entire syllabus in a simple and concise manner. You should read each chapter carefully and make notes of the important points, formulas, definitions, and diagrams. You should also solve the NCERT exercises and in-text questions at the end of each chapter. These questions will help you to test your understanding and application of the concepts.

3. Practice derivations and numerical problems:

   Physics is a subject that involves a lot of derivations and numerical problems. You should practice each derivation at least thrice so that you can write them correctly and quickly in the exam. You should also practice numerical problems from different sources, such as sample papers, previous year papers, additional competency-based questions, and more provided by the board. You should also learn the tricks and shortcuts to solve the numerical problems faster and accurately.

4. Revise regularly and solve mock tests

   Revision is the key to success in physics. You should revise the notes, formulas, derivations, and numerical problems regularly and thoroughly. You should also solve mock tests and sample papers in a time-bound manner. This will help you to improve your speed, accuracy, and confidence. You should also analyze your performance and identify your strengths and weaknesses. You should work on your weak areas and clear your doubts with your teachers or peers.

5. Prepare for the diagrams and practical:

   The physics paper has a mandatory drawing question, either of a graph or a device. You should pay attention to the key features of the diagram, such as the labels, scales, dimensions, and directions. You should also practice drawing neat and accurate diagrams with a pencil and a ruler. You should also prepare for the practical, as they carry 30 marks out of 100. You should know the aim, theory, procedure, observations, calculations, and precautions of each experiment. You should also be familiar with the viva questions and the practical file.

By following these tips and strategies, you can ace physics in CBSE Class 12 board exams. Remember, physics is not a difficult subject if you study it with interest and dedication. All the best!
