Prelims Strategy

To ace Prelims questions on DAE and DST, a meticulous approach to factual recall is paramount. Begin by creating separate fact sheets for each department. For DAE, focus on its establishment year (1954), direct reporting to the Prime Minister, and key institutions like BARC, NPCIL, AEC, IGCAR, and AMD.

Memorize the core objectives of the three-stage nuclear power program. For DST, note its establishment year (1971), its placement under the Ministry of Science & Technology, and its statutory bodies like SERB and TDB.

Crucially, learn the flagship schemes such as INSPIRE and FIST, and their primary objectives. Pay attention to the full forms of all acronyms. A common trap is interchanging institutions or schemes between the two departments, so create a clear mental distinction.

Practice MCQs that test these distinctions, and specifically look for questions on recent policy initiatives (e.g., NSTIP 2020, National Quantum Mission) and major international collaborations. Use mnemonics like 'DANE-ST' (DAE-Nuclear Energy, DST-Science Technology) to quickly recall their primary domains.

Regularly revise these facts, as precision is key in Prelims.
