QUIZ personnal self-training

Hello Everybody!

I am very new on Drupal (less than 2 weeks), so please forgive me if I sound stupid...

I am trying to build a website where french students could come and train/learn english vocabulary.
I feel that I could use QUIZ to do that but I am very very very very lost...

My aim would be to have the students come on the site, signin, and just train without writing:

1- A question is asked: A french word or expression.
They think about it and answer without writing, just for themselves.

2- The answer is already loaded but hidden.
