Preparation Strategy & Essential Additions
Current Affairs: This is crucial. Supplement your static books with a daily reading of The Hindu or The Indian Express. Monthly magazines like Yojana or Kurukshetra are also highly recommended for government policy insights.
CSAT (Paper II): Do not ignore this qualifying paper. Use A Modern Approach to Verbal & Non-Verbal Reasoning by R.S. Aggarwal for reasoning and practice previous years' question papers to build speed and accuracy.
Previous Year Questions (PYQs): Analyzing the last 10 years of UPSC Prelims papers is non-negotiable. It helps you understand the exam pattern and the "language" of UPSC questions.
Recommended CSAT Resources
Reasoning: Analytical Reasoning by M.K. Pandey or A Modern Approach to Verbal & Non-Verbal Reasoning by R.S. Aggarwal.
