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.

QUICK INSTALL ============= For the impatient, here is a basic outline of the installation process, which normally takes me only a few minutes: 1) Move the Moodle files into your web directory. 2) Create a single database for Moodle to store all its tables in (or choose an existing database). 3) Visit your Moodle site with a browser, you should be taken to the install.php script, which will lead you through creating a config.php file and then setting up Moodle, creating an admin account etc. 4) Set up a cron task to call the file admin/cron.php every five minutes or so. For more information, see the INSTALL DOCUMENTATION: http://docs.moodle.org/en/Installing_Moodle Good luck and have fun! Martin Dougiamas, Lead Developer
