Ad Words Certification and now SEMPO Offering Agency Training Certification

I for one have taken the Google Adwords Test, and felt it is great to do but not really built for agency's. Furthermore, Google is constantly changing things around, making this test obsolete quickly. In addition, SEMPO is now offering a test. Again the idea is great but this business is ever evolving and requires us to do our own studying and test ourselves. These tests really do not prove anything. What are your thoughts?
