Rampant cheating has been reported during the school leaving examinations in Pakistan's Karachi city, the media reported on Wednesday.
Students used mobile phones as well as "notes" to copy at several exam centres, Geo TV reported.
"Despite a crackdown on WhatsApp groups where solved papers are circulating, they continue to be accessed in certain exam centres," the report said.
On Tuesday, desperate authorities imposed prohibitory orders to prevent groups from gathering at examination centres across Sindh province.
This was aimed at preventing strangers from entering the centres and barring everyone from using or taking mobile phones inside the premises.
But when Sindh Chief Minister Murad Ali Shah and Education Minister Jam Mahtab Hussain Dahar visited several exam centres, they found smartphones with students and even an invigilator, Geo TV said.
