would this be suitable for an education institute/course creator?

for example, with the English Pro, can this be used to test and assess students' language ability in an interview/let them practice conversations?

--
is there a way that the platform can be embedded onto my own site or make interview invites an automated process for all students in a course etc, rather than sending out the link every time?

--
how are AI credits calculated please? both for creating the interview/test and for assessing performance?

thanks
