To make an appointment (if you have not used this service before), first register with an email address by clicking on an appointment slot and opening the registration form. This only needs to be done the first time. After that, you log on with your email and password, go to the calendar, verify the correct day and take the first available appointment. If you get notification that the appointment time overlaps another, that appointment slot is already filled. To get the first available appointment time , advance the beginning time in the New Appointment window by 5 minute intervals and press "Create Appointment" until you get confirmation. Once complete, the office will have the necessary information when you arrive the following morning. In the meantime, try and get some rest!
