Forms of Teaching

Lectures

Lectures are organized in thematic cycles and comply with the exercises in the course Control Laboratory 1. Direct communication with students during lectures.

Exams

At least three home works must be presented (defended) in the class by randomly selected students.

Exercises

Can be organized if students ask for it.

Laboratory Work

Laboratory exercises are carried out in the course Control Laboratory 1.

Consultations

One hour weekly.
