I want to gamify practice exercises for a grammar course (using Storyline). After so many correct answers, I would like for a character to appear, and when so many more questions are answered correctly, another character appears, etc. Would that be a results slide? Could I randomize the questions (use a question bank) with this scenario? By now I've read most of the user guide on Questions, quizzes, question-banks, and the related, but I'm having trouble putting it all together.
