Candidates can apply practice methods like mock interviews and timed writing exercises to improve presentation skills for UPSC. Conducting mock interviews simulates real exam scenarios and enables candidates to refine their communication and presentation techniques. Regularly timed essays help in managing time effectively while ensuring clarity and coherence in argument structure. Also, incorporating feedback from mentors and peers post-practice sessions leads to constructive improvement. Utilizing video recordings of practice sessions allows candidates to self-reflect on their body language and verbal articulation, enhancing overall presentation effectiveness.
