As described in Wikipedia article,
The Bologna Process is a series of ministerial meetings and agreements between European countries to ensure comparability in the standards and quality of higher-education qualifications.
Universities usually go through a series of supervisions to obtain the certificate that demonstrates the above mentioned quality of education.
These supervisions are, but not limited to, number of classrooms, regulations for exams, lab facilities, etc.
I am particularly interested in oral exam regulations. For instance, my former university had a strict rule:
There must be at least three lecturers/professors during the oral exam, and full voice recording is mandatory.
I wonder if such rule applies for all universities in the Bologna process, or my former university was being over cautious.
