If the student graduates within March, he/she can ask to transform the actual enrolment in Master degree enrolment, paying the stamp fee and increasing the credit load until the 80 credits limit. 
  
• enroll part-time anticipating Master degree courses following the procedure above with a 36 credits limit. Then, after graduating, the student will enroll part-time on Master degree with the registration of anticipated credits. Every enrolment involves a maximum 36 credits plan of study. For the second enrolment the student will have to pay for credits and stamp.
