Groan ... Gave my first in-class CBT today for 200 students over 5 rooms. Organisational headache, plagued by slow system responses & I definitely need more helpers -- when a problem arises in a room (a) they need to look for me and (b) I need to be able to leave my room to help! Overall we had 2 system errors leading to failed submission, 6 failed logins doing their test on paper and a dozen students showing-up at the last minute claiming they didn't know their allocated time slot and these had to be squeezed-in at the end. This amounts (in my reckoning) to a technological success! Then (afterwards) I discover that I have accidentally flipped a true/false answer so have to manualy correct the tests :-( Now that's a costly error!
