Romanian school timetable problems

[rapsy]

I generet schedule with 28 teachers and 16 classes .
- No thanks pt.ca cls.5 not always start at 12, although the class is free .
- In the class . 8 am class occupied 12 two days a week and gives me a schedule of 7 hours per day. I have info. , Phys. and chemicals that have separate rooms and I could have hours. Fail .

Example: class 8D - info - prof . 12 - activ.427 - wish Wednesday,
                             - Phys - Teacher 15 - activ.230-231 - wish Tuesday 11 and Wednesday,
                             - Chemistry - Prof. 16 -activ.248-249 - wish Tuesday 12 and Thursday,

I tried ' favorite activity has slots " do not all go .
I think it should be an option " two consecutive activities " but with different teachers and different specialties . For ex . consecutive info - physical or info - chemistry.

Thanks for the help .
