What Is The Best Way To Link A Score To Level Completion Time

[DokieMaster]

Say that you have a series of questions History/Math etc., and you want to base the score on whomever correctly completes all the questions the fastest. The person who answers everything correctly the quickest gets a higher score than someone who misses some or even someone who also answers everything correctly but takes longer to do so.

Lots of ways you could do this, could have a bonus which gradually goes down on either each question or the whole thing.
F.ex just set a value to the maximum amount of points for each question, let's say 20, and then subtract one point each second until the minimum, let's say 10.
So you get at least 10 points for the right answer, but if you get it right already after 3 seconds you get 17 etc.
Or you could do it for the entire thing, like a bonus 200 which goes down by 1 each second and added when your done.

You could also make it smoother by gradually declining the bonus.
For the first example you set a value to 20, then always set it to ((value*0.99)+(10*0.01))
Then it goes down faster at the start and slows down towards 10.
The reward should then be round(value) to avoid the decimals.
