Teaching methods

Live classes, exercises sessions, homework, studying from the book and from the handouts

Assessment methods and criteria

There will be tests towards the half of the semester and in the end of the semester. The exam will be both written and oral if it will be possible to do exams in a classroom, otherwise it will be an online test.
