Prepare Prelims and Mains together during the first phase.
Do not ignore CSAT because it is qualifying; practise it consistently.
Start answer writing early and improve gradually.
Keep current affairs focused on syllabus-relevant issues rather than collecting excessive notes.
Give adequate time to the Optional Subject because it contributes significantly to the Mains merit score.
Use maps, diagrams, examples, data, constitutional provisions, committees, and case studies to enrich Mains answers.
Practise time management repeatedly before the Mains examination.
Avoid continuously changing books and resources.
Use the latest official UPSC notification and syllabus as the final source of truth.
