For the ethics paper in UPSC, candidates should focus on resources like *Lexicon for Ethics*, *Public Administration* by Rajni Goyal, and case studies that demonstrate ethical dilemmas in real-world scenarios. Furthermore, understanding the *Constitution* and *basic human values* is essential. Analyzing previous years' questions helps identify trends in topic focus and expectations. Engaging in discussions around ethical issues can also enhance critical thinking, enabling candidates to craft well-informed responses grounded in ethical principles.
