Which of these courses is least likely to be offered in specialty school?

Without knowing the specific specialty of the school, it's impossible to give a definitive answer. However, a course least likely to be offered in a *specialty* school would be one that is broad and general in nature, like a survey of world history or a general introduction to psychology. Specialty schools focus on a particular area, so a course that isn't directly relevant to that area is less likely to be offered.
