I have about 400 students. Now I want to divide them into 2 groups (based on what time they go to the class). I could do it manually, but it takes time. So, is there a way to let students choose a group?
One way I can think of would be to use enrolment key for groups. But the problem is students are already enrolled and have some grades. Can I unenrol them and let them enrol again?
Is there any other way?
