Certificate Widget-Changing the Score

I searched through previous entries and it looks like this question may have already been touched on, but I need more clarification.

I have a tutorial that was shot in manual recording mode, showing screen shots from within an application. I have "exercises", having users click on Click Boxes to complete the exercise and move forward (I do NOT have any questions slides).

According to a previous post, you must have a question slide in your tutorial for the score not to read "0%". I do not have any question slides-if this is true, can someone help me with going about adding at least one question slide in the tutorial to make sure a "valid" score appears on the certificate? I do not want an entire training community to get nervous when they see "0%" on their certificate.

I will take any and all help. Thanks!
