Family members can offer crucial support during a candidate's UPSC preparation in various ways. They can provide emotional encouragement, helping to relieve stress and bolster motivation during challenging times. Practical support, such as assisting with daily chores or creating a conducive study environment, can help candidates focus better. Additionally, sharing knowledge or discussing current affairs can contribute to a richer understanding of subjects. Setting up a supportive home atmosphere is vital, as it fosters a sense of security and provides the necessary space for intensive study and reflection throughout the preparation journey.
