Hi,
Many thanks for wonderful software.
We have 9 periods a day from Monday to Friday. Some classes have subject combinations, and some don't. There is a class (IGCSE 1) which I am having trouble with. That class has a choice of 11 subjects but the greatest one can choose is 9. When I input activities that make the total duration of that class greater than than 45 (total number of periods for the week), it doesn't create a timetable. I am thinking it should work because some student sets (subgroups) don't share some subjects so those ones should be able to do it simultaneously.
Your help is greatly appreciated. Thank you.
Thank you for the appreciation!
I saw you automatically divided the year IGCSE 1 by only 1 category with 1 division. I saw that you added a subgroup containing "French" into the "English" group.
The best approach: consider each individual choice as a subgroup and add it to the group. Or each individual student = a FET subgroup.
For instance: year 1 contains 4 choices (Mat, Phy, Che, Eng) and 10 students (Liviu, ...). Liviu chose to do Mat and Che. Add year 1, in it add 4 groups: Y1 Mat, Y1 Phy, Y1 Che, Y1 Eng, in Y1 Mat add subgroup Liviu, and then in Y1 Che add existing subgroup Liviu with a double click in FET (you don't need to write again "Liviu", just click "Add existing" and double click on "Liviu").
It should work if you do like that.
Many thanks for you swift reply.
I thought I did that. For example, IGCSE 1 year has the IGCSE 1 Science and IGCSE 1 Humanities. Under these, I have subgroups which represent the various combinations each student is doing. Then I create a group for each subject and put the subgroups in there.
Maybe I attached the wrong file. Will take a look.
I found the root of my error. For future reference, mine was because the number of FET hours for the day was an odd number (9). Once I changed it to 12 or 6, everything worked as normal.

I am sorry, but I don't understand.
I had done all you suggested before you said it. But I still couldn't generate a timetable beyond a certain number of student FET hours (checked from the statistics). My school does 9 periods a day of 40 minutes each. So I instead try 12 periods a day with 30 minutes each and it worked for me.
In the 9-period approach, the system couldn't schedule two mutually exclusive activities at once. Maybe if students who do literature and additional mathematics are mutually exclusive, normally the system can schedule simultaneous activities involving these two subjects in the same time slot.
But my problems went away when I instead divided the school day into 12 periods.
Hi! The issue is likely because the total scheduled subject periods for IGCSE 1 exceeds the available 45 periods in the week. Even if some subgroups don't overlap, the software must fit all assigned activities into the same slots, and exceeding 45 periods causes a conflict. To fix this, make sure the sum of all activities per subgroup doesn't go over 45. Try using subgroups more precisely or ensure that combinations for any one student never surpass the weekly limit. Let me know if you need more detailed steps!
