Your exams will definetly go ahead even if the College is closed to other students.
You should turn up on time and go to the Hall: check the
timetable if you've lost yours.
If you miss one of these exams you will have to re-sit it in June when it will be a lot harder because it will have been a long time since you were taught the unit and you will be busy with other subjects. If year 11 students miss the Physics exams this month you will only have ONE shot at passing them in June,
i.e. no chance to re-sit.
