Tips for Preparing Important Questions

1. Understand Concepts Thoroughly: Before jumping to solving questions, ensure you have a solid grasp of the theory.
2. Refer to NCERT Textbooks: Most exam questions are based on NCERT. Ensure you’ve thoroughly studied these books.
3. Practice Numerical Problems: Physics is not just about theory; solving numerical is equally important. Focus on practicing questions from past year’s papers and sample papers.
4. Focus on High-Weightage Topics: Topics like Kinematics, Laws of Motion, Work, Energy and power, and Gravity are generally more critical.
5. Use Diagrams and Derivations: Practice drawing accurate diagrams and writing step-by-step derivations, as these often fetch marks.
