Diagram-Based Questions (DBQs) are a critical part of the Class 12 Physics exam. They evaluate a student’s ability to represent physical concepts visually, interpret experimental setups, and analyze graphs. DBQs cover all major topics in the Physics syllabus, including mechanics, electricity and magnetism, optics, semiconductors, and modern physics.
Practicing DBQs ensures that students not only memorize concepts but also understand them deeply and can apply them in experimental or theoretical contexts.
