Are there options to purchase textbooks from outside if they are not included in the Learning Kit?

If specific textbooks are not included in the Learning Kit, they may not be required for your child’s curriculum. However, parents are advised to review the checklist provided in the Learning Kit to ensure all materials are included. If an item is not checked in the list, it is because the item is not required for your child’s curriculum.
