Creating the school timetables often feels like solving the never-ending puzzles. Generally, class overlaps, teachers get double-booked, vacant classes are unavailable, and last-minute changes create chaos. Administrators spend much time, sometimes many hours or sometimes many days in developing and fixing these conflicts manually. A small mistake can disrupt the whole timetable scheduling, so administrators spend hours in calculating and maintaining the schedule. This long process not only wastes the time but also affects teaching quality, student learning, and the productivity of teachers. Now schools have been shifted to an All in One School ERP Software and have saved 70% of their scheduling time by generating the timetables in minutes, detecting the conflicts automatically, and updating the scheduling instantly. This process is a complete transformation in the way of operating the schools.
