A daily study schedule for UPSC preparation should include focused study blocks for different subjects, ensuring a balanced approach. It can be effective to allocate time for current affairs, revision, and mock tests. Mornings may be ideal for tackling challenging subjects, while afternoons can focus on general studies and optional subjects. Including short breaks to recharge is crucial, as is a review session to consolidate what has been learned each day. Additionally, aspirants should set achievable daily goals to stay motivated and track their overall progress.
