competition installation

I have created a contest at: [login to view URL] with a simple Gravit Form. I want to make a konkurrance with 13 questions that can be switched to new questions and answers, when I make new contests. Once visitors have completed the responses, they progress to a page that tells how many correct answers they had and I will be able to write a text like: Your knowledge is OK, but you are advised to attend the course .. . There may already be a plugin that can be these things, I have something more luxurious simply reg such competition implemented on my side. It is important that they are relatively easy to translate into Danish. I'll also be able to mail to everyone who participated and to tell who won, when konkurrancen finished.
