title: Rails gem for adding quizzes to my rails application
body: <p>I started by writing my own quiz handling module, but then I realized I needed a lot more options. I was adding just multiple choice questions, but I need short answer questions, fill in the blanks and so on. I tried looking for a gem that would do that but could only find <a href="https://github.com/runtimerevolution/survey" rel="nofollow">Survey</a> which only provides MCQs. Are there any gems out there that can help me add quizzes to my application?</p>
  
  <p>By add quizzes I mean, to allow a user through the application to create a quiz with different types of questions and define their answers, and then other users will be able to answer them.</p>
  
  <p>Thank you,</p>
