I'm sorry someone rooked you into taking an MT course. AND, this does not sound like a good course to begin with if you take only exams on a computer with no transcription practice. Doesn't even sound like you're hooked up to a foot pedal on your husband's computer, correct? Learning some medical terminology will NOT prepare you for MT'ing.
Gee, I just can't believe this. :(. People are going into MT.
