Type of course unit:required
Year of study:Not applicable - the subject could be chosen at anytime during the course of the programme.
Work placement:There is no compulsory work placement in the course unit.
Recommended study modules:none
Assessment methods:A credit is granted on the basis of two projects assessed Pass (10p or 5p) /Fail (0p), midterm written test (score at least 50%) and active participation in labs (at most 2 missed labs). Credit is required for admission to the final exam. Passing written final exam requires at least 50% score. Course grade is made on the basis of the final exam, midterm test, projects and active participation: A <100 – 110>; B <90 – 100); C <80 – 90); D <70 – 80); E <60 – 70); F <0 – 60). The examiner may shift the grade by 1 step in both directions. The course cannot be taken during overseas internship.
