CBSE Class 11 Physics unit-wise weightage:

Students in our country have always had one goal in mind: to finish the CBSE syllabus as quickly as possible and achieve higher grades, particularly in Class 11 and 12. As a result, little emphasis is placed on whether or whether students can use their knowledge in real-world situations. As a result, it was decided to incorporate questions that would allow them to demonstrate their knowledge and abilities. 

Competency-based questions are the name for this type of question. Students' problem-solving, analytical, and critical thinking skills will be put to the test with these problems. In the paper, there is no overall choice. However, one question with a weight of 2 marks, one question with a weight of 3 marks, and all three questions with a weight of 5 marks have an internal choice. The unit wise weightage for physics is given clearly in the table below:
