What is interesting about exam invigilating? I have done it as part of my day job, and found it excruciatingly boring. You can't take a book to read, and it is a cross between stress in case anything goes wrong and having absolutely nothing to do for hours at a time.
I can see that it is a useful source of extra money, and that it can be done at your own convenience, but interesting?
