Prelims Strategy

Focus on memorizing specific schemes and their delivery models: Digital India components, Aadhaar applications, DBT mechanisms, Common Service Centers functions. Learn constitutional articles (21, 39b/c, 243G, 243W) and amendment details (73rd/74th).

Create comparison charts for traditional vs modern models, centralized vs decentralized delivery. Practice identifying service delivery models from scheme descriptions. Remember key terms: citizen charter, Sevottam model, single window, co-production, network governance.

Use elimination technique by understanding what each model emphasizes - traditional (hierarchy), NPM (efficiency), digital (technology), PPP (partnership), citizen-centric (participation).
