I can only tell you what the timetable was like last year.
There were never more than 3 lectures on any given day, usually only 1 or 2. Three days out of five I was done by 2pm. Seminars often ran a little later, so every couple of weeks there was a day or two where I didn't finish til 5. No seminars or lectures ever, EVER, go on past 5pm.
No more than 12 maximum contact hours a week, so lots of spare time to get hours at work in.
