Hi Phoebe Ridgwell. Welcome to Grokker! When you say "courses I am on", I believe you are referring to the workouts from the yoga program that you joined. Assuming so, you can find the next scheduled workout in a few areas. The first area is if you go to grokker.com. On the left side of the screen, you will see "Your Next Video". This is the next workout you should be doing. If you click on that video, on the right hand side, you have an option to click the program. That will give you a list of all the videos within that program.
In addition, you may find your next scheduled video by going to your calendar either from your homepage at grokker.com or through your "My Profile" - "Calendar".
If you are looking to find videos from the Yoga Challenge, you may click "Go to Challenge" from your homescreen. This page will list all recommended yoga videos for the challenge.
Here are a few yoga programs that you may consider joining:
