Freestyle skiing is one of the more interesting sports in the Olympics. Scoring is based off of many different aspects of the event.
In the Moguls it is mainly based off of turns, the speed and the difficulty of jumps and tricks performed. For aerials it is based off of how difficult the trick is the landing of the jump and the takeoff and form.
For Slopestyle it is slightly more loosely based mainly on the overall execution of the run and difficulty but also by the judges. There are not any fixed scores but it is still judged the same way for all skiiers.
Next is the Halfpipe again scoring is based on difficulty and execution but also by height off the halfpipe. Another is Big Air in this the main factor is how far any given skiier can go but also the tricks that they perform during the jump.
