Additional information:

Przedmioty obieralne są dobierane co roku, na postawie bieżących trendów w nauce i technice oraz potrzeb rynku pracy.
Wykłady oraz ćwiczenia dobierane są indywidualnie przez prowadzących, tematyka jest zatwierdzana przez Dziekana ds. studenckich.
Liczba miejsc na niektórych przedmiotach jest ograniczona, dlatego w przypadku większej liczby chętnych, brana będzie pod uwagę średnia ze wskazanych przedmiotów inżynierskich.
