Before Generate, user can also determine which slot in the timetable to be excluded temporarily. Exclude Slots are slots that you do not want the Included Sections to be slotted in (Example: user will like to fill up all the slots on Monday to Thursday first while excluding all the Friday slots. Friday slots will only be open when all the slots from Monday to Thursday have been filled up).. Excluded slots will be highlighted in Black colour. You can exclude just ONE SLOT (EXCLUDE IN THE SLOT), Room, Day and Time.
