Leader boards

Hi 

I’m looking for some help with using leaderboards on quizzes. I have project at the moment where learners will need to answer as many multiple choice questions within a given time frame. I want to run this as an incentive so would like the leaderboard to show the top 10 and also the individual learners score. 

I’ve looking to use a Google sheets however the code I have was written by someone else and no longer works. Does anyone have any ideas on how I can create my leaderboard?

I’m new to working with Java scripts so any advice would be great.

Thanks 

Stuart.
