Hello Cheryl. Have you tried with a real (or test) student account rather than trying with a teacher account? It is probably not registering your score as you have editing teacher permissions. Also - unless you really need to see which students have only viewed the Quiz but not done it, you don't necessarily have to have 'View' as an activity completion condition. If they make an attempt then they will automatically have viewed it.

Hello Alan. As a native *British* English speaker, I did enjoy your video and thought the exercises were well thought out - although I am assuming you have made it for those learning American English, since as someone called Mary, my name is not pronounced the same as marry or merry 
When you say you want to share your tutorial , do you mean by downloading it an offering to others to use? Such as other teachers? You might like to explore moodle.net
Hello Vaya. There are two reports - a report for Activity completion and a report for course completion as in the Course completion status block You can indicate activity completion for all activities students need to do but you can select only the ones they have to do that count towards their final grade by selecting them for course completion - and then only those will appear in the course completion report for example in the Course completion status block. There is more information in the documentation Using Course completion
Hello Michael. I am not sure I understand your issue - the words Course completed and You have completed the course and Congratulations! should already be translated if you use the French language pack so you shouldn't have to translate them. Can you go to Site administration >Language >Language customisation, choose French and then completion.php (as Patricko suggests) and check if you have the translations>
Hello Matthew and thanks for posting here. Hopefully other Moodlers will have some ideas. There is a plugin called Stamp collection https://moodle.org/plugins/mod_stampcoll which is normally used for rewarding students (giving them a "star" image manually) but you can upload your own image to better suit the idea of demerits. It is worth exploring, except that I believe it is used in a course context by individual teachers rather than site wide. If I think of something else, I will post back.
