University career’s guidance for Spain and abroad:
Baccalaureate students receive international academic guidance. We work on their strengths and professional interests to discover what they want to do in the future through career’s guidance sessions. Following this, their options are studied at an international and national level and they are helped to prepare the application (collection of documentation, preparation for exams, and other requirements specific to the programmes to which they apply).
Participation in fairs of foreign universities is also offered, such the UK Universities Fair organised by the British Council.
