  • To prepare for the Prelims and UPSC Mains, I recommend reading the NCERT books and making two sets of notes – one set of shorter notes and another set of more descriptive notes.
  • To ensure appropriate preparation in advance of the Prelims exam, it is suggested to simultaneously work on both Prelims and Mains material. It is recommended to identify the areas with overlap between the two syllabi, and prioritize those topics first.
  • It is wise to select an optional subject for the IAS exam based on one’s aptitude, interest and experience. However, it is important to keep in mind that certain optional subjects have a significant overlap with the General Studies syllabus in Mains. Therefore, one should take their time to thoroughly research and understand the syllabus of the optional subject before making a final decision.
  • Above all consult the standard books for each subject as outlined in the IAS exam book list and the provided Current Affairs notes, NCERT notes and other resources in the links below.
  • It is essential to adequately prepare for the CSAT paper in Prelims and Ethics paper in Mains, as well as the two qualifying language papers in Mains. Please note that a failure to obtain at least 25% in them will result in disqualification from the IAS exam process, even if you have performed well in all other papers.
