I am a new Moodle user and my question might be silly.
I have got multiple courses and each course is taught by different teacher.Teachers can create their courses but problem is while adding students they are able to see students of other teachers as well.
There are two ways to solve my problem:
1. Remove Add Student access of Teacher to a course. Let it be managed by Admin only
2. Teacher can only add his/her students not others.
Can you please let me know how I can achieve both?
