Shawn,
You know I was told before I went that like David said lots of rejections and several will be right on the edge of rejection by the code they supply. So, I went into this looking for porosity that measured .374" when .375 is rejectable. I didn't find any questions like that at all. All of mine were very much acceptable or rejectable. I did notice as David said the tools were very cheap and the dial calipers were way off and I had to zero them before starting. Some of those sample welds you will say no way i'd let that go, but you must remain objective and go by the code. If the code says it is acceptable then accept it and visa versa. Hey don't sweat over it too much, you'll have plenty of time to finish this part. It's the other parts that will eat up your time if you don't move along with the answers you know and come back to the ones you aren't sure of. The NDT parts were fairly easy, I thought, but I've been in NDT for a while and was somewhat familiar with most of the methods of testing. Know your UT and RT, I had several questions about these methods. For MT, they had a picture of a MT yoke and the question was "what is it?".
Anyway, they have about six different tests that they hand out in your testing room, so don't try to cheat, you'll only cheat yourself. In the "Hands on" part they issue a test kit, all of the peices of that kit have serial numbers on them and you have to put all this info at the top of your test.
Maybe this will give you an idea of what to expect,
John Wright
