Things to Keep in Mind When Studying for Physics in Class 12

  • Focus on NCERT Textbooks : The NCERT Class 12 Physics textbook comprehensively covers the syllabus and serves as the primary resource for the board exam. Ensure you understand each chapter thoroughly.
  • Memorize Key Formulas : Physics involves numerous formulas, and having them at your fingertips can significantly speed up your problem-solving process. Create a formula sheet and revise it regularly.
  • Practice Derivations : Understanding and practicing derivations is crucial. Aim to work through each derivation at least twice to reinforce your understanding, which will help you recall them during the exam.
  • Prepare for Drawing Questions : The Physics paper typically includes a mandatory drawing question, such as a graph or an instrument diagram. Pay close attention to the key features of these drawings to maximize your marks.
  • Simulate Exam Conditions : Practice solving previous year's Class 12 Physics question papers within a three-hour timeframe. This not only helps you get accustomed to the exam format but also prepares your body and mind for the actual exam conditions.

Is physics hard in class 12?

The difficulty of CBSE 12th Physics will vary depending on your skills and limitations. While some students find the topic difficult, others find it to be rather simple. The easiest approach to figuring out how tough CBSE 12th Physics would be for you is to start studying and see how you perform.

Which topics are removed from Physics 12?

Topics such as Electric Charges and Fields, Current Electricity, Magnetism and Matter, Alternating Current, Wave Optics, and others have been removed from the chapters of the CBSE Class 12 Physics Syllabus.

Is the 12th easier than the 11th?

In comparison to class 11, class 12 is easier. Because of the extensive topic curriculum, you will encounter several challenges when you finish your 10th grade and enter the 11th grade (unless you have passed your 10th from the ICSE board.) But you gradually grow acclimated to the extensive material in the 12th grade.

How do you get 90% in physics?

The important physics class 12 CBSE subjects, such as magnetism, electrostatics, electromagnetic induction, and optics, should be well-prepared for since these units often include problems. Study, review, and respond to as many previous year material science papers from CBSE class 12 as you can.

Which chapter is difficult in physics class 12?

Heat and Thermodynamics is perhaps the most challenging but also crucial subject for JEE Main Physics. Students often struggle to answer questions about the subject if they are unable to understand the application portion of the material.
