Kokonaisuudet, joihin opintojakso kuuluu
Suoritustapa 1
It is possible to pass the course without taking the exam by completing the mandatory assignments and gathering enough activity points. The highest grade without exam is 3. Grade can be elevated by taking the exam. Tasks included into the coursework: (1) Simulation assignment (mandatory) (2) Antenna design assignment (mandatory) (3) Online tasks/exercises/homework (certain amount of activity points is required to pass) (4) Exam (optional)
