I can't find a verb that would correspond to the following:
"I take the class ABC" or
"Have you taken/took the class ABC"?
The intent is to ask whether a person was has ever been enrolled (and subsequently completed) a class, as opposed to asking about whether a class has been completed (i.e., not "He completado la clase"). A direct translation would have me use tomar, but I don't know if it would convey the same meaning ("Has tomado la clase?").
Thanks,
Zach
