If a health condition arises during your studies that makes it difficult for you to study and take exams, you may consider applying to your Student Administration Office for a temporary suspension of your studies . (Any such period would be excluded from the term for loss of student status).
If you are regularly enrolled, you can apply to your Student Administration Office for an extension to the duration of your studies, thereby pursuing your university career for a longer time than originally envisaged, without being regarded as “fuori corso” (i.e. past the envisaged time for completion of the degree course).
