Drama is neither sad nor funny but it can be both its like a soap Opera, in a general term though drama can refer to the Theatre atrs, like at school you belong to the drama department
performing arts is probobly to signify its not just classes but an intent to perform, or generaly music or theatre that is performed as an art form
and theatre arts would pertain only to theatre not band or choir and all thing theatre related like musicals, or plays.
Hope that answers some questions
if these are all different classes i would go for all to be frank and then see wich one to major, because as an actor it really helps to have your foot dappled in all the performing arts, make yourself a triple threat as the saying goes, sing, dance and act. LOL
