## How to Score 100 in Physics Class 12 CBSE?

To score well in the CBSE Class 12 Physics exam, focusing on chapters and topics according to the chapter-wise marking scheme is essential. Here's a detailed strategy table to help you allocate your study time effectively.

### How to Score 70 in Physics Class 12 CBSE [Theory]?

Scoring a perfect 70 in Physics, a subject that seamlessly intertwines the abstract with the tangible, may seem daunting for many CBSE Class 12 students.

However, with a methodical and strategic approach, this aspiration is not just a dream but a tangible goal. Here's a detailed guide to help you embark on this ambitious journey:

Finish Each Chapter Thoroughly:

• In-depth Understanding: Ensure that you've comprehended every concept in detail. This doesn't mean just reading through the text but actively engaging with it — questioning, understanding, and revising.
• Practice Numericals: Physics has numerous numerical problems. Regular practice can help in understanding underlying principles and applications better.
• Make Notes: As you proceed with each chapter, jot down critical points, formulas, and concepts in your own words. This exercise not only aids memory but also helps in quick revisions.

You Must Know Important and Unimportant Topics:

• Chapter Weightage: As discussed previously, knowing the chapter-wise marking scheme can be an asset. Focus more on chapters with higher weightage.
• Sub-topic Importance: Even within chapters, not all topics carry the same importance. Teachers, guidebooks, and online resources can provide insights into which sub-topics are often asked in exams.
• Avoid Overlooking 'Unimportant' Topics: While you should focus on important topics, don't completely ignore the so-called 'unimportant' ones. A holistic understanding ensures you're prepared for any surprises in the exam.

Assertion-Reason/Case Study:

• Understand the Format: Assertion-reason and case studies test the depth of your understanding. You need to be able to apply theoretical knowledge to practical scenarios.
• Practice Regularly: Unlike straightforward questions, these require a mix of conceptual clarity and application. Regular practice can help you get familiar with the kind of logic and linkage required.
• Use Supplementary Material: Sometimes, the NCERT textbook might not be enough for these questions. Rely on supplementary materials or reference books for additional practice for assertion-reason and case study-based questions.

Previous Year Questions:

• Trend Analysis: Going through previous years' question papers will give you an idea of the pattern of questions, their difficulty level, and the trend of important topics.
• Timed Practice: Attempt these papers in a simulated exam environment. This helps in time management and prepares you for the pressure of the exam.
• Evaluate Thoroughly: After attempting the paper, review your answers. Understand where you went wrong and rectify those concepts. Over time, you'll see patterns in your mistakes, which you can work on.
• Revise from Mistakes: Often, our mistakes teach us more than our successes. If you make an error in a particular concept or formula, revisit the chapter, understand the concept again, and practice more problems related to it.
