So his cabinet was locked, and Olly was still holding the box in his hand. He did exactly as the instructions had said and opened the box. It locked, like the cabinet had been. Why? They had already proven they could use the spell by opening the cabinet. He supposed it was just reinforcing the lesson or test or whatever. Olly didn't mind. He knew he would have no problems doing the spell again.

"Alohomora." The box unlocked easily. Olly opened it to find just a small slip of paper with numbers on it. The numbers that would take him through the door. He did as he had seen a few others and made his way over to the door. As he passed, he noticed how far each student had gotten. There were all mostly at the same place, just opening their boxes to get the code. Soon, they would all be done with the test and moving through the now locked door. Olly wondered what was behind it. Hopefully not another test. But he would know soon enough. The second year typed his code into the pad beside the door so it would let him in.
