TLDR;
This video provides a detailed plan to improve problem-solving skills in Physics, addressing common issues such as understanding concepts but failing to apply them, memorizing formulas without comprehension, and struggling with complex questions. It emphasizes clearing basics, consistent practice, and effective learning techniques.
- Clear Physics basics and NCERT
- Solve 10 questions daily
- Practice and understand derivations
Introduction [0:00]
Many students face challenges in Physics, such as being unable to solve problems despite understanding the concepts, or freezing during exams even after memorizing formulas. Simple questions are manageable, but any slight variation causes difficulty. The video aims to provide solutions to these problems, demonstrating how to approach and solve Physics questions effectively.
Addressing Common Excuses [0:25]
Students often blame the difficulty of the CBSE paper or attribute success to innate brilliance. However, toppers achieve high scores by following a strategic plan, not just because they are naturally gifted. The video aims to provide a similar plan for average students to excel in Physics.
The Importance of Consistent Practice [0:57]
While many videos advise solving numerous questions, this video suggests a manageable goal of solving 10 questions per day. This consistent practice results in approximately 300 questions per month, which is ideal for covering three chapters thoroughly. Solving 100 questions of varying types per chapter is essential for adequate preparation.
Clearing Your Basics [1:45]
The first step to improving in Physics is to clear your fundamental concepts. If you have backlogs from 11th grade or have missed important classes, it is crucial to address these gaps. Many questions in 12th-grade Physics require the application of 11th-grade concepts. For example, understanding dot products and vector operations is essential for solving certain problems.
The Role of NCERT [2:38]
Reading the NCERT textbook is crucial for Physics, as CBSE sets papers with conceptual questions and theory directly from NCERT. Even numerical problems often incorporate 11th-grade basics before applying 12th-grade formulas. Relying solely on advanced books like HC Verma or DC Pandey is unnecessary; focus on mastering NCERT and solving a variety of questions.
Effective Class Participation [3:31]
Actively participate in class by asking questions. Don't worry about being laughed at for asking simple questions. Instead, focus on understanding the material. Observe how your teacher approaches and solves numerical problems, noting their initial steps, reasoning, and application of concepts and formulas.
Active Revision Techniques [4:43]
When revising, actively recall concepts instead of passively reading like a newspaper. Use class time as active self-study by engaging with the material. Hide the solutions to questions solved in class and try to solve them independently, then compare your method with your teacher's to identify mistakes.
Practice with the Right Resources [5:18]
Use a good question bank like Oswal Book Question Bank, which includes various types of questions that CBSE is currently asking, including competency-based and conceptual questions. The question bank is organized topic-wise, allowing you to solve related questions immediately after learning a topic. It also includes previous years' questions, providing insight into CBSE's question patterns.
Additional Tips for Success [6:11]
Solve 10 questions daily, including easy, medium, and hard problems, starting with easier ones to build confidence. Understand derivations to know the origin of formulas and develop a deeper understanding of the concepts. CBSE sometimes frames questions based on derivations.

Step-by-Step Numerical Solving Process [7:11]
To solve numerical problems effectively, break down the question into smaller parts, create a mental frame, and highlight important keywords. If necessary, draw a diagram. Identify what is given and what is asked. For example, in a question from the 2025 CBSE paper, the problem involves two point charges and an external electric field.
Applying the Concepts: A Detailed Example [7:47]
The example question involves calculating the change in electrostatic energy when an external electric field is applied. First, identify the given values and conditions (switch off and switch on). Use the formula for energy in the switch-off condition (K Q1 Q2 / R). Then, consider the switch-on condition, where additional energy due to potential is generated (q1v + q2v). The change in electrostatic energy is the final energy minus the initial energy.
Deriving Potential from Electric Field [11:30]
To find the potential (v), use the given electric field (e) vector. The relationship is given by E vector dot dr vector. Apply basic vector concepts from 11th grade, such as the definition of the unit vector r cap (r vector / modulus of r vector). Use the dot product formula (ab cos theta) and the fact that cos 0 = 1 when the vectors are the same. Simplify the expression to find the potential and then calculate the change in electrostatic energy.
Final Thoughts and Encouragement [14:35]
Solving questions requires sitting down and following the steps outlined in the video. Don't be afraid of Physics; treat it like any other subject. Clear your basics, solve at least 100 questions per chapter, and solve 10 questions daily. Believe in yourself and commit to completing what you start. Commenting "I promise to solve 10 questions every single day" will set up accountability.
