CBM Grades Readme.txt file This version is NOT GDPR ADAPTED
Tony Gardner-Medwin (a.gardner-medwin@ucl.ac.uk)
v 2.7.02 (23 Aug 2014) for Moodle 2.7, 2.7.1, 2.8-3.4

This plugin directory ('cbmgrades') belongs in /moodle/mod/quiz/report .
It displays scores appropriate for interpreting performance when using CBM.
It optionally displays responses for individual questions.
Scores can be based either on the whole quiz or on just those questions which the student has chosen to respond to.
This latter is appropriate when a student uses the quiz for self-testing, choosing which Qs s/he wishes to work with.

The original plugin (v.1.2) was written for the CBM behaviours modified in Moodle 2.6 and also works with
CBM in core Moodle in Moodle 2.3+. It is compatible with the patches available at TMedwin.net/cbm/moodle to
improve CBM behaviour in Moodle 2.3+, but is not essential with these.
Please report any issues to me Tony Gardner-Medwin (a.gardner-medwin@ucl.ac.uk)
