First, to Aden, because of his nonparticipation, I can give no points.
Second, to Christina, for her creativity, I thought her writing was well done, and she was creative in her description of how she handled the maze. Her descriptions were vivid and lively, and showed a level of originality that I liked. There were some overlaps with canon elements. 3 points for the writing, 2.5 for the answer to the riddle, 1 point for completion of task. 6.5 total points
Third to Abbey, I thought she did an exceptional job, seeing as she is such a young Hogwarts student. She described the emotions of a young student well and how she coped with the tasks, despite her lack of experience. And, as Professor Wilson also notes, she is the only student with the correct answer to the sphinx's riddle. Well done, Abbey. 3 points for writing of the task, 4 points for the answer to the riddle, 1 point for completion of task.
Last but not least, to Selwyn, I also appreciated the creativity, and I thought he showed some use of some background knowledge or resources that were not typical canon knowledge. That was nice to see. I also liked the creativity in how his character coped with the task. It was refreshing. 4 points for writing of the task, 2.5 for the answer to the riddle, and 1 point for completion of the task.
