I'm not whistling because I cheated, the test is common sense... or at least I thought it was. Its just a big joke as the article states.
As for multiple tests being done on one computer... definitely you can. I mean what if one person was the witness for several peoples tests and they all did it at his house/computer...
But honestly some of the online tests are such a joke, one of the more popular websites gave me and my wifes licenses for free because of their own carelessness.
I love when people who have no idea about the internet open an internet business!
As for my in laws, they got the test done at the boat show... and the guy administering the test gave out answers.... not only that... but if you fail you can keep trying with no waiting period... what kind of licensing system is that? make it match a drivers license at least, you can't just keep trying for those!
