Hi N R, I am happy to help!

You can leave a program by following the steps below:
•Logging in to your account via https://grokker.com
•Go to the program page
•Scroll down, on the far right side under related programs there will be a box that says 'Can't Keep Up? Leave the Program' and choose 'Leave the Program' .

Once you have left the program you are able to join a new one.

Hope this helps! If you need further assistance of any kind please reach out to us via email at support@grokker.com
Sincerely,
Loren
