Three activities at the same day, but just two consecutives

[banzsys]

Hello, guys!

I need some help with the following question:

how can I specify to be three activities with the same teacher at the same day, but I just want 2 of them consecutive, i.e, it would has one class not connected with the 2 others?

Thanks!

Hello, banzsys! 

A1 (T), A2 (T), A3 (T). A is activity, T is teacher.

Add a constraint activities same starting day, (A1, A2, A3), 100%.

Add a special activity tag, AT, to A1, A2, A3.

Add a constraint teacher T activity tag AT max 2 hours consecutive (only works if the activities have each duration 1. Otherwise we need to think some more).

Please let me know.

There are three math classes (same teacher), but in order not to get tired I would like two of them to be consecutive and the other to be after another class of another subject.

Yes, exactly; isn't my previous answer solving this?

Note that I do not ensure that two of them are consecutive; there may be A1, another activity, A2, another activity, A3. Is that OK?

Thank you! That's it.
