First Course (Mystery Adventures Pack)
From the Super Mario Wiki, the Mario encyclopedia
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.
