Indian authorities have blocked access to the messaging app Telegram nationwide, a measure taken just days before a rescheduled national medical school entrance exam. The decision follows a significant breach of exam security last month, when test questions were leaked online. Officials believe Telegram was being used to share and distribute leaked exam papers, compromising the integrity of the highly competitive test. This isn’t a complete ban, but a temporary restriction intended to prevent further cheating during the upcoming exam. The National Testing Agency (NTA) requested the block, citing the need to maintain fairness and prevent further dissemination of unauthorized materials. Millions of students are expected to take the exam, which determines admission to medical colleges across India. The move raises questions about online security and the challenges of preventing exam fraud in a digital age.
