"Hello Professor" Rex said as he came into the classroom. He was sad that this was his last year at Hogwarts, but it was time for him to move on. He would be graduating very soon.

Rex listened carefully to the instructions. His first task was to change the teacup in front of him into a ball. What was the spell for that? Rex thought to himself. And then he remembered. As he took out his wand he made a clockwise circle and then a counterclockwise circle while he said the spell he remembered,
Mizurus boru. He focused as hard as he could, and the teacup finally materialized into a ball.

Now on to the next step, to get the ball to levitate and fall into the bucket. "Globo leviosa!" Rex said firmly, doing a flick and swish motion with his wand. He smiled as the ball rose into the air and then landed in the bucket where it belonged. He was doing well so far - yay!

But there was more. There were still two more stations to go through. Rex went on to the next station and saw that he would need to expand freeze one of the two balls which were jumping so happily in front of him and then banish the second one into the box that was placed there. Okay, one thing at a time. Rex knew what the spell was for making the first ball freeze, or at least he hoped he did. ""Immobulus" he called as he pointed his wand and sure enough, the ball suddenly stopped in midair. Rex was on a roll. He might as well take care of the second ball while he was hot. "Depulso" he said, pointing his wand at the ball which was still moving and sure enough, the ball went inside the box without putting up any fight at all. Good.

Now Rex was to the last station. He was supposed to expand and then reduce the range of light on the lantern and then make the lantern appear invisible. "Luxra Magnifica" he said, waving his wand in an X motion. Instantly, the light became much stronger and spread throughout the room. It might be so bright that the other students would have a hard time seeing in here, Rex thought. Better hury and get this done. "Finite", he pointed at the lantern again and the light dimmed back to the level it had been on before.

Rex hoped he could remember the spell to make the lantern invisible. He didn't want to mess up, especially since he had done so well so far. Oh yes, he knew what it was. "Disillusiona!" he said forcefully, tapping his wand on the lantern at the same time. Rex smiled as the lantern became impossible to see, even though Rex knew it was still there.

He had finished the tasks successfully and Rex was happy. With a smile he left the classroom.
