Important Preparation tips for Class 12 Physics
- Physics board exam strictly follows the NCERT textbook as it covers the entire class 12 Physics syllabus. So students are recommended to study from the NCERT Class 12 Physics book.
- Students should have important formulas at their fingertips so that they can answer the numerical questions quickly.
- Students must practice each derivation at least trice so that in the exam it won’t take much time.
- The Physics Paper has a mandatory drawing question either of a graph or a device. Students should pay attention to the key features of the diagram to score full marks on this question.
- Students should solve previous year class 12 physics question papers with a time slot of 3 hours. This will prepare their body and mind for the actual examination.
The strategy to score 90+ in CBSE 12 Physics–
- • Students who are weaker in Mathematics should try to read Modern Physics initially. The Semiconductor chapter is one of the most important chapters as its weight-age is around 8 marks. Atom and Nuclei together constitute 6 marks.
- • The next set of chapters will consist of Dual Nature of Radiation which carries 4 marks. Communication system constitutes 3 marks. Having command over these chapters help students a great deal in scoring higher marks in Physics.
- • Now you need to go for important and difficult chapters like Optics which carries 14 marks in the board exam.
- • In Optics, you need to complete Ray optics first, which is easier to study. In Wave Optics, you should concentrate more on problems of Interference, Diffraction, and Young’s double slit experiment.
- • Current and Electricity is also an easier chapter and it carries 7 marks.
- • If one has not studied Electrostatics and Magnetism till date then it is better to leave these chapters because these two units consume more time than the others. However, these chapters are very important for competitive exams.
- • EMI is another unit that you need to focus on to score well. It is an important unit both for the board exam and competitive exams.
- • Practice the ray diagram and other important diagrams carefully. Drawing and studying will help you understand many topics faster and in an easier way.
- • Try to solve objective problems to make yourself efficient in solving 1 mark questions in the exam; this will be a bonus for you.
