Effective group discussions for UPSC can be enhanced through strategies such as setting clear objectives, time management, and encouraging participation. Establishing ground rules helps maintain focus, while appointing a facilitator can keep discussions on track. Utilizing current affairs as discussion prompts allows for informed debates, deepening understanding of complexities. Participants should practice active listening, ensuring all voices are heard, and building on each other's points. Reflection after discussions aids in self-evaluation, reinforcing learning objectives, and enhancing overall preparedness for the UPSC exam environment.
