In TimeTabler, at 'Check & Validate' there are 12 feasibility Tests.
These allow you to check your Curriculum & Basic Data in various ways, after you have entered your data but before you start scheduling.
Time spent now on these tests, will almost certainly save you time later, during scheduling. Most schools don't run all the tests, but use the ones most relevant to them, or where they know they have had to make compromises in previous years.
Full details of the 12 tests are here:
