## CBSE Class 12 Physics Practical Syllabus and Marking Scheme

Below mentioned are the CBSE 12 physics syllabus and marking scheme for practical exams. Physics is a practical subject hence the curriculum of class 12 physics is divided into theory and practical exam. The students must also solve the CBSE class 12 sample paper for better results and more practice.

Two experiments each from both sections A & B | 8+8 |

Practical Records (activities and experiments) | 7 |

Viva | 7 |

Total | 30 |

### Section A

**CBSE Class 12 Examination 2022-23:- Preparation Tips**

Here are some important preparation tips which will help students to complete the CBSE Class 12 Physics syllabus on time.

- Keeping in mind the weightage of each unit, students should give more time to the units which carry more marks.
- Everyone should make notes of each chapter while studying, it will also help in the revision.
- Students should make a study plan on a daily basis. By doing this they can focus on the chapters in which they are weak or lacking behind.
- Students should also solve the Class 12 Physics sample papers as well as class 12 Physics question Paper which will help them in getting the idea about the pattern of the question paper. Students can also find the CBSE class 11 physics sample paper as well.
- After completing the Class 12 physics syllabus, students just need to revise and practice more.
- According to CBSE class 12 toppers as per CBSE class 12 results, students must solve the previous year’s question paper for 12th physics.
- Before attempting the question paper students must go through the CBSE class 12 syllabus as well as the CBSE class 12 date sheet.

If students will follow the above-mentioned tips for preparation they will surely pass the final examinations and get the best results.
