I want to fulfill one scenario in Moodle.
I want to create batch 11 in which there are multiple students.
Now I assign that batch to Course A for learning.
To handle that batch 11, I will assign User AB to that batch 11 as teacher / manager.
At same time I create one more batch 12 and assign it to Course A.
For batch 12 , I assign User CD as teacher / manager.
Now I want that both batch and teacher can't see other batch activity or other batch users.
How we can achieve this in moodle.
