There are many great websites out there with LOTS of practice Spontaneous problems. A list of those sites is shown at the bottom of this page.
Super-de-Duper Spont Site!
Earning the #1spot on this resource page is an AMAZING Spont resource from North Carolina Odyssey’s Eastern Region that not only goes over the main types of spont problems and provides many practice problems….This site actually has videos of teams solving spont problems!
These videos are brand new in the summer of 2015, and are very informative for coaches, teams, and even judges who want to see how a Spont problem is actually run and solved by a team.
