The schedules for the Summer University courses will be available from mid-march. The schedule is specific to each individual Summer course.
We link to the schedules from this page (mid march) or you can look them up in TimeEdit (mid-march).
In the meantime
Until mid-march, for an indication on how your course was structured last year; how many days of teaching, how many hours a day and so on, you can look the course up in TimeEdit.
In TimeEdit you click "Search the schedule" and adjust the dates so they point back to Summer University last year.
There is no guarantee that the schedule will be the same each year, but it might be an indicator to help you decide on whether or not a summer course is a good idea for you.
