If you're not familiar with all the different kinds of jumps in figure skating NBC's website has a great section showing all the different kinds of jumps, complete with little videos of each jump. Also there's a guide to the new scoring system and a glossary of terms you may not know (as Craig said during ice dancing, "Twizzle? Isn't that a type of candy?")
