To stop pupils cheating in Algeria, the government has taken the extreme measure of cutting internet access across the whole of the country during exam time.
Mobile and web connections were stopped for two hours on Wednesday to coincide with the start of two high school diploma tests.
The blackouts are expected to continue for the duration of the exam period, which runs until Monday, following a crackdown by officials.
The 2016 exam season was marred by widespread cheating, with questions published on social media before or at the start of tests.
Last year, authorities asked operators to shut down access to social media.
