With a large number of Central Board for Secondary Education (CBSE) students having applied for revaluation of answer sheets of the recent class 12 exams, many teachers from CBSE schools in Bengaluru too have been deputed for revaluation duty. This has forced schools to revise their timetables and swap classes of teachers on revaluation duty with those available on campus. If necessary, extra classes will be conducted once the teachers return from revaluation duty.
