one class that appeared useless when i signed up for it but was actually one of the most useful courses I ever studied in school was a speech class. I have never shied away from public speaking but I know a lot of people that are absolutely terrified of it. This course helped us to get our thoughts together and present them in a confident and concise manor. To this day it is one of the only classes that I took in my 7 years of college that I actually remember a lot of what we studied.
