problem with fortnight

[mbj]

Good evening,
I have a problem to generate employment in my
university.
my problem is: I have two subjects: M1 and M2
to be studied by students per fortnight
even a class divided into two groups G1 and G2. So I
want to have this:
Week 1: G1 => M1  and G2 => M2
Week 2: G1 => M2  and G2 => M1
Week 3: G1 => M1  and G2 => M2
etc.
thank you for your help.

Add one weekly activity, with subject M1_M2 (a dummy subject), and students G1+G2 (two students sets). If you need to occupy two rooms, add one dummy activity, same starting time with this one.
