Students who finish their exam papers at 12.10pm will have to wait in school until 2.30pm before using their subsidized e-transport cards to go home.
This is after some parents raised concerns that their children who sat for exams in the morning could not go home after finishing their paper due to restrictions on the use of e-transport cards.
Subsidized e-transport cards were earlier restricted to only be usable from 6.30am to 9am, and from 2.30pm to 5pm, to stop students who were abusing these cards to skip school.
Permanent Secretary for Education Anjeela Jokhan says they cannot do everything for everyone and students will have to spend the remaining two and a half hours in school.
Jokhan says it is also safer for the students to stay in school and prepare for their exams rather than leaving school after 12pm.
