Hello :)

I'd like to create a plugin with a quiz :

20 questions and 10 are chosen randomly with a time control of 60 seconds. If the answer is right, he wins 1 point otherwise 0.

Then, his number of points must be shown on his profile. And, I also want to make a raiting and put it in the first page of my website.

I'm a beginner, so I would be very grateful for your help ! :)
