The impact of peer pressure on UPSC aspirants can be both positive and negative. Positive peer influence fosters a sense of competition and encourages diligence among candidates. Study groups can lead to shared resources and collaborative learning, enhancing overall preparation. Conversely, negative peer pressure may lead to undue stress or distraction. Aspirants might feel compelled to adopt others' study methods or schedules, which may not resonate with their personal learning styles. It's essential for candidates to maintain their own pace while finding a supportive network to mitigate negative impacts.
