Can I attempt Debrief Quiz Only one time?
Will Debrief Score will affect anyhow consideration for the scholarship for Crio launch plus?

I didn’t know that multiple choice was allowed and I had submitted already.

Yes we can only attempt once as answers are shown after that. Regarding score, I don’t think it will have that much of an impact in the long run.
