Creating School Timetable

I'm currently setting up the ST environment for the demonstration school we'll use to customize ST for Nigerian schools.

The school's time table starts on other days from 8:10 to 2;00 with 40mins period, however, on Monday, the first class period starts by 8:45 and end 9:20, but school end by 2.00, while on Friday the school time table starts by 8:10 with same 40mins period, but class closes by 1.00................SOLVED

Which type of Timetable should I use rotating cycles or what? SOLVED

Secondly,

The intervention module is giving this error;

The page you are trying to access is not available

Please try the following:

   1. Make sure that the Web site address is spelled correctly.
   2. Go back and try another URL. SOLVED

Also is there any way to change the layout of groups, courses, etc presentation on the web interface to use more of the space?
