Calcutta Girls’ High School that was conducting Class X and XII pre-board exams on the campus on Wednesday decided to hold the remaining papers online as a precaution amid the rise in Covid cases.

The online exams will start on Thursday following the same timetable, the school said.

“We have told parents that because of the sudden spike in Covid-19 cases, we are discontinuing the on-campus exams,” said Basanti Biswas, the principal of the school.

The pre-board exams in the school had started last week. In each class — X and XII — barring eight to ten students, everyone had been present, an official said.

Three city schools had to shut their campuses for about a week after students and a teacher tested positive for Covid-19.

Schools had been shut since March 2020 as a precaution against Covid and reopened for Classes IX to XII on February 12.

“Though we are following all safety measures in the school, the number of cases is steadily rising in the city and the school did not want to take the risk,” an official of Calcutta Girls’ said.

Teachers of several schools had advocated for on-campus exams so students of Classes X and XII could practise writing pen-and-paper tests before they write the boards.
