Rajasthan Board Class 11 Physics Syllabus
Rajasthan Board Class 11 Physics Syllabus

 

Rajasthan Board of Secondary Education (RBSE) was established in the year 1957. The syllabus prescribed by the board has undergone drastic changes keeping in mind the changing times. RBSE has been proactive in structuring the syllabus of all the subjects of Class 11, given the significance of the same in a student’s academic career and to give them a better understanding of the subjects. 

 

Rajasthan board’s major goal is to equip students with the necessary information and skills to compete in national competitive tests. The curriculum has been designed to give the students a deep knowledge of the concepts and topics. After Class 11, the next stage in higher secondary education is Class 12. Therefore, the syllabus has been designed to help students in further studies.

 

The textbooks published by the board are structured on the lines of the respective syllabus designed by the board. Also, these books have all the necessary chapters and topics with good explanations. Rajasthan Board has come up with a comprehensive syllabus for Class 11 Physics as the subject finds various applications across a vast industry verticals and in daily life. The syllabus has been set by the experts under the guidelines of the board.

 

It has been ensured that the syllabus provides students with necessary skills to clear the board exam with flying colors and do well in their higher studies. Therefore, students are advised to study Physics syllabus in detail to build a strong foundation in the subject and prepare themselves for upcoming exams.

Rajasthan Board Class 11 Physics syllabus has been designed really well. It will help students in planning their study time, break down the parts of the syllabus, and prepare well for the exams.

The total marks for the subject are 100, divided into two parts: theory paper and practical exam. The theory paper is of 70 marks and the practical exam carries the remaining 30 marks. To score well in the RBSE Class 11 exam, a student should be well-aware of the syllabus and prepare the subject thoroughly.
