Why isn't the course working?

We have a few suggestions on how to troubleshoot the Online Judges Course.

• Take the course on your computer or switch devices: Users tend to have more issues when they try to take the course on their smart phone or tablet. 

• Try a different browser: Chrome and Firefox are best. 

• Clear your browser cache 

• Check your internet network and connection: Some networks may have firewalls that prevent the course from playing. If you are attempting to take the course at work and are unsuccessful, try accessing it from home, your affiliate, or from another location and see if that helps.
