Wow, scarily similar to what happened in my AS Business retake on the 21st May.
There were 3 invigilators.
We had encountered them all before from AS exams. One of them had a reputation for being a bit dopey.
First off, she gave us the question sheet with no answer booklet, giving me two question sheets instead.
Secondly, she stopped some people writing to check their details on the sticky tape thing.
Thirdly, for basically the whole exam, the duration on the board said from 9:15 to 10:45 when the exam was only 60 minutes.
Lastly, she stopped one person taking the same test in a different row 5 minutes before she stopped us. We were waiting for her to come over and collect our papers but she just stood over him as we carried on.
In my English exam, one of the invigilators came up to us after we had completed it to ask if she had given us the right exam! It's a bit late.
