It was only 8:40 when he arrived at the barn near the Care of Magical Creatures classroom and Mason wondered how he had gotten there so early because he usually arrived just in time.

Perhaps it was because of the fact that he started to understand the layout of Hogwarts castle and had even found a few secret short cuts he could use when traveling from class to class.

"Good morning, Professor" he greeted the moment he spotted him standing next to the blackboard. Next thing, Mason went to find a seat on one of the beanbags and opened his book. Which was not the CoMC textbook by the way but the 'Counter curses' book he had lend from the library yesterday.
