General Science forms an essential part of many competitive exams in India, including those conducted by the Odisha Sub-ordinate Staff Selection Commission (OSSSC) for various positions like Revenue Inspector (RI), Assistant Revenue Inspector (ARI), Amin, SFS, and ICDS Supervisor. To excel in these exams, candidates must have a strong grasp of fundamental scientific concepts. Here, we present the top 30 General Science multiple-choice questions (MCQs) to help candidates prepare effectively.
