First Course is the first level of the Coin Challenge Pack B in New Super Mario Bros. 2, as well as the thirteenth DLC level in the game.
The level begins with a few appearing/disappearing blocks that can be triggered via a ? Switch. It leads to another room where Mario must take the bottom left Warp Door. Another segment with a vertical climb and a few Boos and + Clocks appears, and the correct door is at the highest point. The next room features several one-way gates, with the correct door at the very right. The very next room has what appears to be three doors, with the correct door at the top left with what appears to be a window. The next segment features many appearing/disappearing blocks, followed by many Roulette Coin Blocks and another door. The following segment consists of Boos and a Gold Ring, and that segment follows with an area that leads directly to the Goal Pole.
- Star Coin 1: In the first room, the Star Coin is located on the top right of the page, and can be accessed using the uppermost platform that appears using the ? Switch.
- Star Coin 2: In the second room, the player should take the bottom left door. After reaching the end of that room, the next room contains the Star Coin after several flippers. It can be accessed by hitting the Question Switch near the bottom of the room.
- Star Coin 3: In the room with the disappearing and reappearing platforms, the Star Coin is located in an area on the top right of the room.
