The nationwide examination, conducted by the West African Examinations Council (WAEC), will run until May 11, with 620,141 candidates from 20,395 schools expected to participate.
The council says it is taking a firm stance against examination malpractice and has warned candidates to comply strictly with the rules throughout the examination period.
“Candidates found engaging in any form of malpractice will face severe sanctions,” an official said, stressing that possession of prohibited materials, including mobile phones, will not be tolerated.
