Hello Liviu!
I have a problem to ask you.
I want to create a new combined class from a set of given subjects, with the purpose of students in different classes studying the same subject to create a new class as shown below. So how can I make the constraint on FET fastest and most effectively?

As usually, I am afraid I do not understand. Maybe you mean dividing a students year according to categories?

No problem, but I would prefer you to attach pictures here (max allowed size is 512 kb).

And I still don't understand... I am sorry.
