This report plugin allows Administrators to set up arbitrary database queries
to act as ad-hoc reports. Reports can be of two types, either run on demand,
or scheduled to run automatically. Other users with the right capability can
go in and see a list of queries that they have access to. Results can be viewed
on-screen or downloaded as CSV.
The main difference from the standard Moodle multiple choice question type is in the way that grading works. When creating the question, the teacher just indicates which choices are correct. If there are n correct choices, then the student scores 1/n for each correct choice. If they select too many choices, then incorrect choices outweigh correct ones.
