First Course (Coin Challenge Pack B)

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.

Layout
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.
