The document contains 4 schedules for a preschool's classes across different weeks. The 1st schedule is for Monday to Friday and lists teachers and their class assignments for each time slot. The 2nd schedule follows the same format for a different set of classes and teachers. The 3rd and 4th schedules repeat this pattern for additional class arrangements. It is noted that the schedules will repeat twice every term and that the EFL lab can be booked during the 9th week each term.
