This is to remind students that appointments can ONLY be cancelled personally with the presentation of your appointment booklet. You may come personally or you can send a friend, but you always need to bring your booklet to the lab for the cancellation to be signed. NO "VIRTUAL" CANCELLATIONS (mail, facebook, blog) WILL BE ACCEPTED. Remember that considering emergencies and unforeseen situations you have up to 2 absences without cancellation. But more than two absents implies suspension for a month. Please revise the Appointment Regulations in this Blog.
