Aspirants can exchange resources, study techniques, and insights about the syllabus, enhancing their understanding. Group discussions help clarify doubts and deepen knowledge through collective problem-solving. Moreover, maintaining a competitive yet supportive environment can motivate candidates to perform better. Regular interactions can also alleviate stress, making the preparation process more manageable and less isolating.
