We have created 6 new students each teaching year to mimic all tutor groups for all 6 houses giving an array of options for 6 students in GCSE and A-Level. Alongside to debug options and each class.
When making teacher timetables manually, sometimes this duplication can occur. Thus seeing a class twice in the same period with two different teachers
Example where 08PE02 has two teachers
In Years 7-11 where there should be no free periods, if there is a free period there is a period missing.
For example, in this debugging scenario: Monday Period 4 is missing when Year 9s have no free periods
