Science & Technology — UP Police Constable Study Notes

Overview

Science & Technology is a high-scoring and frequently tested area in UP Police Constable exams, typically contributing 8–12 questions in the General Knowledge section. This topic covers India's achievements and developments in space exploration, defence technology, information technology, biotechnology and recent scientific breakthroughs. Questions are factual and current-affairs based, focusing on names of missions, organizations, scientists, recent launches and technological milestones from the past 18–24 months.

Success in this section requires regular reading of science-related current affairs, knowledge of key Indian organizations (ISRO, DRDO, CSIR, DBT), major missions and programmes, and awareness of India's technological self-reliance initiatives like Atmanirbhar Bharat in defence and Make in India in IT. Students must maintain a running list of recent launches, test-firings, discoveries and awards, as these form the bulk of exam questions.

The topic rewards systematic revision — create a timeline of major developments, memorize full forms of organizations and missions, and track India's global rankings in technology indices.
