I managed to find a couple sample tests to practice model for cswp segment 1 prep (2008 sample and 2010 sample cswps) and I can crank both out pretty well, but that has been after lots of repititon so I dont feel like it proves that i am ready since Ive done them over and over, and i feel like I need a fresh thing to model. Are is their any other resource besides the two samples?
I would download other folks' models and try to make chages to their design. Understanding design intenet and how a part was modeled helps to understand the best way to make changes to them. Then just take the test. This is the best way to know what's up. I'm betting you will do great but if not you will know what to expect next time.
