The practical work or group presentations for me were the worst thing that happened to me in college. In my case I had to take care of work that my classmates had not even started to do and to make it worse the professor said that in a real job, if someone does not do anything you have to get used to it and complete it yourself what that person has not done because we are supposed to be versatile and cover someone else's position.

Obviously it's something that generated stress and made me hate that subject. Aside from not enjoying it at all. To make it worse, it was 2 levels, which luckily I completed by my own effort, no thanks to others.
