Thanks MoP They sent me an example model with the test and it did it int the cut into and not clip through method so I'm doing that on the major detals but things that aren't as obvious I'm going to just avoid it.
That's what I figured, thanks guys. Do you think that I should go this route on my art test (the example file they sent me had it done this way)? I'm trying to look as professional as possible and didn't know for sure if having it clip through was the 'noob' way of doing it. Thanks again!
