I never knew you were a student teacher.
All people who become teachers have to student teach before they graduate,or the used to.And if you got a really bad grade(yes,we were given a grade and it was worth almost an entire semester's course of 6 classes!), you weren't allowed to graduate with a BEd.,nor take a teaching job.It could also lower your GPA to such an extent that it kept you out of grad school.
