Hi,
I have a class 1.A and students in the class are divided into groups A1 and A2 according to their level of English. And similarly for a second foreign language (groups N1 and N2).
I've come up with a FET division:
Year Groups Subgroups
1.A Language1 A1
A2
Language2 N1
N2
1) This division allows activities for A1 and A2 to take place simultaneously. That's OK and it is good for me.
2) The division allows activities for A1 and N1 to be scheduled at the same time. That's not what I want. Can I fixed it in any other way than using the constraint "A set of activities are not overlapping"?
Thank you!
Note: I try to understand the FET XML format as I export my data to the XML.
No, ibrahim, he wants something else:
Divide year 1.A by two categories, category 1: A1, A2, category 2: N1, N2. This way both groups 1.A A1 and 1.A N1 will contain subgroup 1.A A1 N1, so they will have common students and their activities will be impossible to be simultaneous.
I attach a small example, which is impossible because I added a same starting time constraint for activities of 1.A A1 and 1.A N1.

Thank you! That's exactly the kind of argument I wanted to know. You have literally made my day :-)
Yes you are right
