Other practical payment details and options
- Primary payment method information: payments are to be made to the school; bank/wire transfer details are provided by the Business Office. When paying by wire transfer, any bank charges or transaction costs must be added to the payment amount so the school receives the full invoice amount.

Payers should reference the student's surname and invoice number in the payment reference. Contact the Business Office for precise bank details and current exchange instructions.
