Hexagon is arguably the hardest course in the game, especially in Adventure Mode. Many people have had trouble with this course, and thus Hexagon is a great obstacle in accessing the final boss, since you need to finish everything in Pro difficulty.

The goal in Hexagon is to remain consistent in catching ghosts as quickly as possible, while also retaining maximum possible score output. Skip or bomb through any mazes to get to Power Pellets more quickly, especially early on.

Be sure to wake all the ghosts in the maze before eating the power pellet that spawns below the ghost hub. More ghosts on each train = more points.

Once you get to the harder mazes, like the one below, it's best to corner ghosts at specific locations. Pinpoint at either side or any corner of the maze to catch them, and plan accordingly. Bomb if/when necessary.

The maze above shows that the middle portion is not the best place to catch ghosts. Take either the left or the right side to your advantage.
