Question formulation is crucial for effective study habits in the UPSC context, as it promotes active learning. By creating their own questions, candidates engage deeply with the material, reinforcing their understanding and retention. This process encourages critical thinking, allowing for exploration of topics beyond surface-level information. Additionally, formulating targeted questions helps identify knowledge gaps, guiding further study. Working in groups to challenge each other with questions can enhance collaborative learning and discourse. Ultimately, effective questioning transforms passive studying into an engaging and productive experience.
