How long will it take to create all the courses?

This depends, among other things, on the method you choose to create your courses and the size of your institution. As a rough guide, most schools with fewer than 50 teachers create their timetables using EDT in around two weeks, and those with more than 50 teachers in three weeks (or a little longer for very large institutions)*.

*Survey conducted by Index Education in October 2018 among 8,755 establishments in possession of EDT soft.
