If a cancellation notice is given more than 24 hours  prior to the scheduled exam, a $100.00 cancellation fee will be charged.  If a cancellation notice or a no show less  than 24 hours prior to the scheduled exam, a $250.00 charge will be made. 

  If the examinee fails to show for his exam without notice, the client will be responsible for the full exam fee.
