Preparing for questions on administrative reforms in UPSC involves a thorough understanding of past reforms and their impacts. Aspirants should focus on significant reforms like the Rajiv Gandhi Commission, Second Administrative Reforms Commission, and recent changes in policies and governance structures. Engaging with case studies, current events, and analyzing government reports can also provide deep insights. It is beneficial to synthesize this information into concise notes. Regular revisions and discussions with peers help to solidify this knowledge, and keeping abreast of contemporary issues in administration is crucial for context in the examination.
