The standard Moodle quiz module will do this just find if you use a theme that works well on mobile devices.

Well, these are the core question engine tables. They are not really quiz tables.

I think you are better off trying to manually alter the table definitions to match what they should be. There is not an automated way to do it.

First you will need to throw away all the attempt data, which means deleting all rows from

• quiz_attempts
• quiz_grades
• question_usages
• question_attempts
• question_attempt_steps
• question_attemtp_step_data

then check/alter the columns in those tables.

But, if the question tables got messed up, then really you need to check all tables in your database to make sure they are correct.

In the navigation block, Quiz -> Results -> Responses and Quiz -> Results -> Statistics will get you started.

If that is not enough, http://docs.moodle.org/dev/Overview_of_the_Moodle_question_engine#Database_tables

To be clear, AMOS only gets initialised with the strings for a plugin when a new version of the plugin is uploaded after this feature was implemented about a month ago. So, if the scheduler module was last updated in the plugins database longer ago than that, the strings will not be there yet.

That is MDL-36369.
