You cannot claim a diploma for the preparatory classes you have taken. However, your preparatory classes are equivalent to 120 ECTS-compatible credits (European Credit Transfer and Accumulation System) and give you direct access to the 3rd year of a Bachelor's degree and the opportunity to obtain a Bachelor's degree.
To be eligible, you must hold a recognised 3-year university degree or equivalent, accredited to a minimum of 180 ECTS credits.
You must therefore indicate in your application form, in the 'type of diploma' field 'Licence/Bachelor', in the 'length of study programme' field a minimum of 3 years and include your preparatory years in the start and end dates of the study programme.
In the 'comments' section, you can specify that your degree was obtained due to your preparatory years.
I benefited from a "Passerelle" (acedemic reorientation) before obtaining my bachelor's degree. How can I indicate my diploma?
If you changed your study path and were able to enter directly into the 2nd or 3rd year of a new course after completing only part of your first course or a 2-year degree, you should select "Licence/Bachelor" as the type of degree in your application.
You must enter "3 years" as the length of the study program and include all years leading up to the year you received your degree in the start and end dates.
In the comments section, you can mention that your diploma was earned through a "passerelle" (academic reorientation).
I've got my bachelor's degree due to an extra year after my two-year diploma. How can I indicate my diploma?
If you started directly in the 3rd year of a Bachelor's degree after completing a 2-year program at EQF level 5, you should select "Bachelor's/Bachelor's degree" as the type of degree in your application.
Enter "3 years" as the length of the study program, and include the full period of study, starting from the first year of your initial 2-year program up to the year you obtained your degree.
In the comments section, you can explain that your degree includes the first 2 years at EQF level 5.
