Castle Rushen High School says it’s been forced to cancel lessons for Year 9 students because of staff absences.
In a letter to parents, it says Year 9 pupils shouldn’t go to school tomorrow (Thursday).
Year 10 students should go to school as normal at 9am on Friday for a mock maths exam – but leave school at 11.20am during the morning break.
The school has apologized for any inconvenience.
