Our program does something similar. We have a hands-on clinical supervision course in which we are responsible for "mock" supervision of one of the first year students in the program. Upon completion of the course, we are eligible to supervise students in the university clinic in later semesters. If this is something of potential interest to you (and that your program may be considering), then you may wish to reconsider. If not, then no big deal and nothing major lost.
My doctor says that I have a malformed public-duty gland and a natural deficiency in moral fiber, and that I am therefore excused from saving Universes.
