-Lectures
-Lab. exercises
-Web-based learning
-Assignments

The course is based largely on laboratory work that is practical application of lectured material. Students work on constructing electrical circuits, then assemble them and conduct measurements on them to verify if they work as intended.The Flex Students (flexible race) must come to campus twice for two days to conduct the laboratory exercises.

Coursework requirements:
There are 16 to 19 exercises in the course. 3 of the exercises in the fall semester and 7 of the exercises in the spring semester must be submitted according to given deadlines. Approval of these must be given to be allowed to take the exams.

All laboratory exercises are mandatory. It is also mandatory to write and submit a lab journal for all laboratory exercises. In addition 2 laboratory report must be submitted according to given deadlines. Approval of these must be given to be allowed to take the exams.
