I just took (and failed) my 462. I went into it blind just so I could meet the free retake deadline. I got 550 out of a needed 700 (with no prep). A big difference I noticed is that the score report is WAY more broken down than the 461. So I had very detailed info on what was good and what was bad. As for the tests being worthwhile? I don't know. What I do know is that it will give you a great insight to the product and *hopefully* help people (like us) get their foot in the door.
