different hourly scan of lessons

[Pg]

Sorry for my horribile english!

Afternoon classes are from Monday to Friday (5 days).
my high school is divided into two locations within 3/4 km
each location has a different hourly scan of lessons: the first seat start at the hour and the second seat to half.

I made a first attempt:
-on ' the days of the week ' I set 10 days: the first 5 days indicating the first location,the second 5 days the other location;
-on "the hours of the day" I set: the "hour 1" at 13.00 Hour (seat 1) while the "Hour 2" at 13.30 (seat 2), and so on.

Unfortunately I saw that in the final screen I FET calculates hours 30 minutes, not 60 min (no consequential hours putting in the correct way), forcing me to put a lot of constraints ...
do you have any suggestions?
Thanks

Do you mean that you need to force some activities at 13 and so on and other at 13:30 and so on? Then you may add only two constraints activities preferred starting times, for two activity tags, AT13 and AT1330. Then add the corresponding activity tag to each activity.
