Four students, who had to appear for the highly competitive NEET (National Eligibility cum Entrance Test), died by suicide this week in Tamil Nadu. The entrance exam for medical courses will be held today across the country amid a surge in coronavirus cases. Two students -- Aditya and Jothisri - were found dead yesterday. Twenty-year-old Motilal, son of a trader in Tiruchengode town of Tamil Nadu, could not clear the entrance exam last year; he was to re-appear today.
