The deadline for the first-year students is 9.30 pm and for others, 10.30 pm. Soon after the deadline is over, authorities check the register and conduct first verification soon after the deadline and the second time again at 12 am. "By the time we conduct our second check on missing students, it would be well past midnight," said the chief warden, adding how difficult it is in some eight hostels that house more than 700 students.
