Sadly if I had one day with the question set I could get 100% the next day too. If they are letting the questions get out then our certifications will be worthless. Actually mine will be worthwhile because I learned but all those who cheated will be worthless causing companies to ignore mine. They need to do a better job of protecting the questions if they are in fact getting out.
There are lots of stuff they could do. Every test is diferent, vary question order, vary answer order, vary questions, vary answers, word answers diferently, ... Do good job and the cheaters will not have motivation to steal cause it doesn't work so well. And people will not buy stolen tests.
But I use the tests as a learning tool rather than an end in itself. So they help me personally to learn and excell.
