I have some courses with guest access and self registration. If an authenticated user goes to the course users grades are not saved without enrollment. That's why I have added guidance to enroll first. There's a link to enrol/index.php etc.
Here's an example:
This is quite complicated and I'm planning a block that shows the users status and enrols an autenticated user with one click. Or is there already another simple way to solve this?
There's also a self made block that shows best total grades. Do you think t's worth of sharing?
