Staff Designer, Bendix Spicer Foundation Brakes I attended the AGI 3 day test prep training in Chicago. The training was presented by both Norm and Mark. Without that training I don't think I would've been remotely prepared to take the ASME test. Their knowledge, not only of the test but GD&T on the whole is quite remarkable. Plus they have the ability to communicate that knowledge in understandable ways. I would advise against taking the ASME test without taking the AGI training first. And as one who has now done both I can testify that Mark's prep test is indeed harder than the ASME test. - Brett Darner
