How are you qualified to teach the Latin University Admissions Test?

I am qualified to teach Latin for the University Admissions Tests, beause I passed the Latin Admissions Test of the University of Oxford with a "highly impressive" mark, as one professor of Latin (and Classical Greek) at the University of Oxford has said.
 

N.B. It is for personal reasons that I did not attend the University of Oxford, despite passing the entrance exams.
