For UPSC Civil Services Examination (CSE) aspirants, Shubhra Ranjan is a household name, particularly for two subjects: Political Science & International Relations (PSIR) and General Studies Paper-II (Polity & Governance) . Her teaching methodology, structured flowcharts, and concise yet analytical notes are considered goldmines by many.

Purchase a single subject booklet (e.g., Western Political Thought) from the official source to understand the style . Then, supplement with free YouTube lectures and create your own handwritten notes. Your own notes, made with understanding, will always outperform a pirated PDF from an anonymous Google Drive.
