Oh and one thing just keep practicing in easy mode and when you think your getting better then change the mode to normal and well you know to hard mode when you think your better for hard mode.
Oh and if your racing online and if you see a blue shell coming at you on the map, just backup and let the 2nd racer to take first place and then he or she will get the bomb shell. But ONLY do that if the 2nd racer is close behind you. Its super funny when I do that to people, because they race in traps, then I go up ahead and win. I bet the person gets mad
