Is there any way to lock my course content in Moodle and share only with my students?
I wish even site admin couldn't see my course content. Can I do that in Moodle?
Hello. I am moving your question to the General help forum.
You can't hide anything from the site admin, but if he/she has correctly set up your Moodle site then you can ensure that only your own students access your course by enrolling them manually and not allowing other students to self enrol into your course. See Teacher quick guide if you are unsure how to do this.
