First Course (Mystery Adventures Pack)

First Course is the first level of the Mystery Adventures Pack in New Super Mario Bros. 2, as well as the twenty-fifth DLC level in the game.

Layout
The level begins with a Sledge Bro and a P Switch, where hitting the P Switch leads Mario underground. Mario must then move back and forth on descending stone slabs with Hammer Bros, Gold Rings, and a chain of ? Blocks with Super Stars. After an ! Pipe and a Red Ring, Mario will enter an area with many different rooms to explore, along with two Warp Pipes each in two of the rooms, one normal-sized one and one small one, that lead Mario to a stone elevator going up. From there, he must keep grabbing Super Stars to take out the Sledge Bros and hitting P Switches to get past the Brick Block enclosures. The stone elevator eventually leads to an area with the Goal Pole.

Star Coins

 * Star Coin 1: In the first chamber on the stone elevator down, in plain sight above a Hammer Bro on the left side.
 * Star Coin 2: In the second maze chamber, Mario must head to the left until he reaches a room with a Boomerang Bro. The Star Coin is high up at the right side of that room.
