A teacher recently sent me a link to this article and pointed me to a section toward the end of the article.
From this article I read the following excerpt:
"When I was going threw the process of becoming a Google Apps Certified Trainer I was taking the required tests on all the Google Apps. The tests run on Google's own system and once you press start you have 90 minutes to finish. Google also gives you all the training materials which are public and anyone can learn from. So I did what any cheating student would do. I started the test in one browser and then opened up the training materials in another browser. When I came to a question I didn't know the answer to I would quickly search for and find it in the training manuals. Basically an open book test.
