On 9-27-11 I was administering a dosage calculations exam. The students were finishing the exam faster than expected. I had instructed the students not to leave the school because if everyone was done early I felt the extra time could be used after the exam to introduce new material. With about 25 minutes left I asked the class if anyone felt they would not be done by 2:30. No-one responded that that would be problem. With 10 minutes left I again asked if anyone would not be finished and, as before no response. I gave a two minute warning that met with continued silence. At 2:31, approximately 50 minutes after the start of the 33 question exam, I collected them. Lakresha stomped down the steps slammed her exam on the podium and stormed out of the room. Several minutes later I saw her in the hall and asked her \"what happened?\". Her response in an aggravated tone was \"I didn\'t finish my test\" and she left the building. Lakresha did not return to school until 9-29-11 at about 8:30
