Cheese Land was hell for me. I had never played the GBA version and I tried what I thought was a shortcut... but what was actually scenery in the distance that wasn't part of the track.
Haha, that's kind of funny. I played it once in 150cc before I got online so I knew what to expect. With the abundance of mushrooms there are some really easy and useful shortcuts at the end that you can learn to help you catch up.
