CBSE Physics Class 12 question papers

The Central Board of Secondary Education (CBSE) physics examination for class 12 is conducted based on the textbooks prepared by The National Council of Educational Research and Training (NCERT). Class 12 physics is a stepping stone for students planning to pursue the subject for higher studies. Physics is one of the key subjects for exams like JEE and NEET.

The subject gets divided into two parts.

Part I consist of the following chapters;

  • Electric Charges and Fields
  • Electrostatic Potential and Capacitance
  • Current Electricity
  • Moving Charges and Magnetism
  • Magnetism and Matter
  • Electromagnetic Induction
  • Alternating Current
  • Electromagnetic Waves

Part II consist of the chapters;

  • Ray Optics and Optical Instruments
  • Wave Optics
  • Dual Nature of Radiation and Matter
  • Atoms
  • Nuclei
  • Semiconductor Electronics

CBSE class 12 students prepare for theoretical (70 marks) and practical (30 marks) examinations. CBSE Physics Class 12 previous year question papers help students understand the model of question papers that might come for their upcoming CBSE Physics Class 12 examination. Practicing them helps one to write the exam effectively and efficiently. Practice the CBSE Physics Class 12 previous year question papers 2021 to score marks for exams like JEE and NEET.

For the CBSE class 12 physics exam, it should be noted that;

In Section A of the question paper, Fill in the blanks and short answer questions have one “OR” question each. The student has to answer one of the given two questions.

In Section B and Section C of the question paper, there is one “OR” question.

In Section D, all the questions are “OR” questions.

In the case of JEE and NEET, both are objective exams.

CBSE Physics Class 12 previous year question papers 2021 will help Class 12 students to focus on critical chapters and topics. Physics is a subject that has equal weightage in both JEE and NEET. Semiconductor Electronics: Materials, Devices, and Simple Circuits, Current Electricity is usually the chapters carrying more marks. The Electromagnetism section has the possibility of more questions, including Electromagnetic Waves, Ray Optics and Optical Instruments, Wave Optics, Current Electricity. Questions are asked from every chapter but depending on each year the weightage varies for each subject. Usually, one question is asked from every chapter. Don’t skip the optics, electrostatics, and Electricity sections. Students are requested not to skip any of the chapters as the weightage may vary year after year.

How should the students approach each type of question?

Here NCERT Physics Class 12 previous year question papers 2021 guide how one should approach the questions for Class 12 CBSE Physics examinations, JEE and NEET.

CBSE class 12 examination

  • Multiple-choice questions

There would be four choices, out of which one is correct. The student should read all the choices and select the right one.

  • Fill in the blanks

There will be single answers to these questions, which do not carry any negative marks. So the student must attempt these types of questions. If a student has read the text at least once, these questions can get tackled easily.

  • Short Answers

These types of questions test the student’s ability to recall definitions, the meaning of terms. Keywords of definitions must get written and underlined to gain marks. The valuation is done based on a few points. For eg: for a 2 mark question, the student is required to write 4 to 6 points.

  • Long Answers

These descriptive questions are an extended version of short format answers as it requires the students to write in-depth answers. Do not forget to draw the ray diagrams, circuit diagrams, and electric field lines if any gets asked. Also, give the directions correctly.

  • Practical Examination

First, complete your records and projects neatly and timely. Since the record of the experiments and activities gives five(5) marks. Be sure to read the whole record and remember all procedures as the same would get asked in Viva, which will fetch you five(5) marks.


  • Both the exams follow an objective type of questions. Note in mind that each wrong answer carries one(1) negative mark. So if the student does not know an answer to a question it is the advice they should not attempt the question, rather than taking a gamble on answering it, which has the effect of losing five(5) marks
