Swiveling my head behind us, I see Umbridge with her wand out pointing towards the falling paper bird. Lowering her wand, she said in that utterly too sweet tone, "good morning, children." slowly walking towards the front of the room while pointing her wand to the chalkboard, she continued, "ordinary... wizarding... level...  examinations!  " Each word enunciated more than the last. "O! W! Ls! More commonly known as OWLs!" She explained turning to face the class at the front of the room. She was treating us like we were in primary school. Not the fifteen year old's that they were. Well I was almost sixteen and that was not quite right due to third year. Everyone who came to Hogwarts knew about OWLs. "Study hard, and you will be rewarded. Fail to do so, and the consequences may be...  severe ." Another threat hidden in that tone. I was pretty sure she did not mean having to retake the exams.
