The Polish grading system in higher education is based on the 5 to 2 scale, where 5 is the best mark and 2 is the worst.
Moreover, students can also be marked with additional signs of + and -. Each of them equals half a point: + means 0.5 more. Some courses, however, are not evaluated on such a marking scheme and for these a student may simply obtain zal. or zaliczenie which means that their workload was satisfactory and they have passed the course.
Nicolaus Copernicus University follows ECTS scheme (European Credit Transfer and Accumulation System), which means that ECTS credits are allocated to course units, lectures, practical works, etc. at each faculty.
To complete successfully year of study, students are obliged to collect 60 ECTS credits (30 credits per semester).
