I am a teacher my exam will be based on teacher assignments only or admin and teacher both?
As Moodle installation fails, I am doing assignments on other moodle platform available at my workplace. So admin assignments are not possible to do.
Moodle-Learning-Management-System Admin-dashboard 03-04 min 50-60 sec
What I will suggest is that you can definitely try out the teacher assignments with 'Teacher' role.
Also, regarding installation failure, will you please share the issues you are facing, either error messages or screenshots so that we can help you to continue with the installation so that you can explore the admin part as well?
