Master's theses are typically graded with either the above scale, or by the Latin system used in high school matriculation exams, see above. Contrary to the upper secondary school however, the grade "laudatur" is typically used very rarely (significantly less than 5% of theses). Indeed, laudatur is often reserved for exceptional students and it is typically awarded for a thesis only once in 5 to 10 years (!). In practice, eximia is often considered as the best grade available and it best corresponds to a grade of 5 in the 0-5 scale.
