What is the general feeling out there on probationers doing cover classes (Yufties, Please takes)? I'm in my sixth week of my probation year and have already had 5 half period cover classes.  The school policy is that as our periods don't allow for a exact 0.7 timetable we should be doing one half period a week to make up for it.  My time table is at 67.56% so i feel i have as full a timetable as really could be expected.  Talking to others schools both probationers and Supporters there seems to a wide range of views, i was just wondering if there was any difinitive one?
