Tim Hunt bb93fc24aa MDL-6340 quiz: avoid reusing random questions between attempts ... There are several improvements over what we had before: 1. We track all the questions seen in the the student's previous quiz attempts, so that when they start a new quiz attempt, they get questions they have not seen before if possible. 2. When there are no more unseen questions, we start repeating, but always taking from the questions with the fewest attempts so far. 3. A similar logic is applied with variants within one question. There is lots of credit to go around here. Oleg Sychev's students Alex Shkarupa, Sergei Bastrykin and Darya Beda all worked on this over several years, helping to clarify the problem and shape the best solution. In the end, their various attempts were rewritten into this final patch by me.		2015-03-26 17:45:49 +00:00
