UPSC preparation does not need an unlimited reading list. It needs the right few sources, read repeatedly.

This list is organised by GS paper. Books marked Core are the main sources to complete and revise. Books marked Reference are for deeper reading or specific doubts. Do not try to finish every reference book.

How to Use This List

  1. Start with NCERTs to build basic concepts in each subject.
  2. Move to the Core book for each subject and read it with SAHAS class notes.
  3. Link current affairs to every topic, using the daily newspaper and SAHAS Daily Current Affairs.
  4. Solve PYQs after each topic to see how UPSC asks questions.
  5. Revise the same Core books at least three times instead of adding new ones.
