Professor Wendy Berger was a young teacher. Hermione guessed that she must’ve graduated only within the past five or six years. One thing that Minerva had gotten right (even though many dismissed it as a joke) was that Professor Berger was indeed a lot of fun. In fact, the good professor was rarely seen without a happy smile on her face as she patiently explained how a spell worked, the proper incantation, or the correct wand movement. She would give a light cheer whenever the students figured out how to cast the spell they were learning about. The class was informed that if they managed to get at least an Acceptable on their quiz, those students would receive a bookmark made from copper-colored fabric with a symbol representing Transfiguration stitched in. For those who received an EE, they got a silver bookmark; while an Outstanding got a gold bookmark plus an invitation to instruct the class on how they accomplished their spell casting.
