Prelims Strategy

Focus on memorizing specific facts: dates, chemical names, legal provisions, and case names. Create a timeline of major disasters with key details - Bhopal (1984, MIC, Union Carbide), Vizag (2020, Styrene, LG Polymers), Jaipur (2009, Oil depot), Mumbai High (2005, ONGC).

Memorize constitutional articles (21, 48A, 51A(g)) and their judicial interpretations. Learn key acts with years: Environment Protection Act 1986, Public Liability Insurance Act 1991, Factories Act 1948.

Practice elimination techniques by understanding common traps - confusing chemicals between disasters, mixing up legal principles (absolute vs strict liability), and incorrect cause-effect relationships.

Focus on recent developments and policy changes post-2020. Use mnemonics for remembering multiple acts and their provisions.
