Form(s) of Assessment


Form(s) of Assessment (additional text)

An overall evaluation based on a 100 point scale, where mid-term exam counts 33 1/3 points, project work counts 33 1/3 points and final exam counts 33 1/3 points. Conversion from 100 point scale to A-F scale according to recommended conversion table. In specific circumstances, emneansvarlig can slightly adjust the limits in the conversion table to enforce compatibility with the qualitative descriptions on the A-F scale.
