I have a Masters Degree in an unrelated field (Sports/Recreation) but I do mention it in my ads because a lot of the courses did directly relate to what I'm doing now and I think for SOME people it speaks to my character (I am hard working and put a lot of effort, work and dedication into my schooling). I would definitely not consider myself better than anyone else and putting it in my ad is just like adding "I'm a mother, I'm a wife, I taught preschool...I have a higher ed degree".
