With CBSE class 12th Board Examination around the corner, the concerned students are seen to be immensely under stress and performance pressure. Since this is the period of the academic session that influences the performance of the students to a great extent. Therefore, whether a student has studied throughout the session or planning to study and excel in the remaining time that they are left with. It’s important for them to shift their regular approach of study to a data-based calculative approach. Therefore, similarly to the other subjects, the most profound way to excel in physics can be deduced according to the marking weightage based Important Chapters and Topics of Physics for CBSE Class 12th Board Exam.
The students who were not able to study throughout the entire year due to some reasons like illness etc. should try to prepare the Important Chapters and Topics of Physics for CBSE Class 12th Board Exams. That carries 43% marking weightage, to help you score at least 33% passing marks. These important chapters are:-
- Ch-14 Semi-Conductor carrying 7 Marks
- Ch-11 Dual Nature of Radiation and Ch-13 Nuclei having a marking weightage of 8 Marks
- Ray Optics which is the 9th chapter and can add 8 marks to your score
And if you get some more time then you should try to cover few topics of Ch-10 Wave Optics with marking breakup as mentioned below:-
- Derivation of young double slit experiment & Numerical based – 3 Marks
- Huygens’s principle – 1, 2 Marks
- Explanation of reflection, Refraction by Huygens principle – 2, 3 Marks
- Polarisation – 3 Marks
In case you want to add few more marks to your CBSE class 12th board result of physics paper, then you should target Ch-1 Electric Charges & Field, Ch-2 Electrostatic Potential & Capacitance, and Ch-3 Current Electricity which carries 16 Marks. Additionally, if you feel comfortable with the studied portion of the syllabus then try to cover up Ch-4 Moving Charges & Magnetism, Ch-6 Electromagnetic Induction, and Ch-7 Alternating Current that have a marking capacity of 14 Marks.
