two-thirds in the morning, one-third in the afternoon

[Abdelhak]

Hello,
I'd like to know if it's possible to apply the following constraint and how:
two-thirds  (2/3) of a given subject's weekly classes must be taught in the morning while one-third (1/3) must be taught in the afternoon, but no later than a given time, e.g. no later than the 2nd period in the afternoon.

Indeed, as Benahmed said in Arabic, you can use more constraints subactivities preferred starting times / time slots.

Thank you Mr Benahmed & Mr Lalescu

You're welcome!

Hi again,
I've another question. Does the software offer the possibility of setting the preferred starting time slots "for a set of activities/sub-activities" "at once", "not one by one"?

[Liviu Lalescu]

I am not sure I understand correctly. You have the constraints activities/subactivities preferred times for more activities, specified by the filter.

[Abdelhak]

I mean, would it be possible to apply such constraint to a an X number of sub-activities of a given activity at once, without having to repeat the action for each sub-activity?

[Liviu Lalescu]

If you have 4 activities (1+1+1+1+1) each, you can add a constraint subactivities for component 2 and one for component 3.

[Abdelhak]

Can such a constraint be applied "simultaneously" to both components, or it has to be done for each component "separately"?

[Liviu Lalescu]

I think separately, but I don't see the problem, since there are few constraints.

[Abdelhak]

in Algerian secondary schools, 2/3 of core subjects' weekly sessions must be taught in the morning while 1/3 is to be taught in the afternoon. Applying that condition using "the preferred starting time slots" separately for each subject takes too much time, that's why I was asking if it would be possible to do it simultaneously.

[Liviu Lalescu]

I am not sure there are too many constraints. But you could add a tag "Core" for each such activity and add only preferred times for "Core" activity tag specified.

[Abdelhak]

The core subjects & their weekly sessions differ both within the same level/grade & across levels/grades, that's why we've too many constraints to set.

[Abdelhak]

I think it'd be great to have a feature allowing for the "simultaneous selection" of multiple subjects (activities) and the ratio of classes (sub-activities) to be taught in a given time slot. That would make it less time-consuming.
