Important Questions for Class 12 Physics – Chapter-Wise Weightage Strategy

Presenting below are some tips and tricks to score well in CBSE Class 12 Physics:

  • Students who struggle with Physics should begin by reading Modern Physics. The chapter Semiconductor is one of the most essential, with a weighted average of roughly eight marks. Atoms and nuclei are for a total of six marks.
  • Dual Nature of Radiation carries four marks in the next set of chapters. Around three marks are assigned to the communication system. Students will benefit significantly from having a solid grasp of these chapters to achieve higher grades in Physics.
  • Now you can start studying the most important and most complex topics, such as Optics, worth 14 marks in the board examination.
  • Ray optics, which is an easy topic to study, must be completed first in Optics. It would be best to focus more on difficulties involving interference, diffraction, and Young’s double-slit experiment in Wave Optics.
  • Current and Electricity is likewise a simple chapter that carries seven marks.
  • If a student has not started with Electrostatics and Magnetism until the end, it is preferable to skip these chapters because they take up more time than the others. On the other hand, these two chapters are critical for competitive examinations.
  • Electromagnetic Induction is another chapter on which you should concentrate if you want to do well. It is a crucial chapter for both boards and competitive examinations.
  • You should thoroughly practise the ray diagram and other relevant diagrams. Drawing and learning at the same time will help you grasp numerous things more quickly and easily.
  • Try to solve objective type problems to improve your ability to solve one mark questions in the examination; this will benefit you.
  • Go through Extramarks’ Important Questions for class 12 Physics section to retain and revise all the important concepts.

FAQs (Frequently Asked Questions)

Although subjective questions from CBSE class 12 science Physics such as “answer in brief,” “identify between,” and “explain in detail” are long, they are the simplest to score since they are open-ended. You can enhance your replies if you have the required knowledge and concept of the questions asked in the exam. Close-ended questions include Multiple Choice Questions, fill-in-the-blanks, Assertion – Reason Questions, and Case study based -cum- MCQs. For these sorts of questions, the response should be explicit or precisely stated in the textbook. If your answers to these questions are wrong, you will straight away get a zero mark for the question. On the other side, if you have a good understanding and knowledge of your entire syllabus, it will become easier for you to score well in subjective and objective questions. As a result, Extramarks offers you a comprehensive course structure and resources to practise a variety of questions.

To start with, write down all of the formulae and practise them regularly so that you can memorise them. In Physics, derivations are extremely important. Retaining the derivations of the formulaewill make it much easier for you to answer the questions on the board. Exam questions will be asked unusually. To comprehend them, you must have a good command of different concepts and applications.

Always concentrate on the topics that carry the most weightage in terms of marks. Topics like sound waves, wave optics, modern physics, and alternating current should be your primary focus. Thermodynamics is one such topic that is covered in both Physics and Chemistry. This is also one of the most essential areas in Physics. A thorough practise of all topics is a must.
