Check if facilities vary with the time of year, whether a charge is made and if there is a time limit on your access. Contact the Careers Service in your home area before you visit, asking what facilities they might be able to offer and whether charges are made. Remember to say where you graduated and how long ago. Be aware that some Careers Services give priority to their own graduates and students. Some Careers Services offer a special service for graduates of any university and college, for which a fee may be charged.
Facilities vary from individual careers guidance to workshops to a structured training course.
