Been running it for about 6 weeks already (we were a pilot school last year) found it has more problems than last year, keep having to restart the postmaster service every once in a while.
Also been using some wireless laptops to run the practice tests on, is anybody using this set up!
also like probably most will find the GUI is total alien to some of the students, and they find it as hard as hell to do some of the tests, the best way I’ve found (muggings here helps out in YR9 ICT lessons) is to have one session going through step by step how to use it, saves a lot of the same sort of questions from students.
