HOLY SHIT, 31 is OK?
I cannot remember what mine was. All I remember is I was the only one taking the test and my recruitrer told me around 100 time on the wa to the test to take my time and check my answers. I cannot remember if we had 2 or 3 hours to take the test?
Anyhow, I finished in around 1/2 hour, checked a few answers and got bored, and remembered something that I had been told about second gussing your answers, so I turned the test in.
The proctor called my recruiter, and he showed up extremeley pissed. He was yelling at me about what a dumb fuck I was and how I'd be lucky to get to be a cook. As he was driving down the road he pulled my test scores out, looked over at me, and asked "How would you like to go into the nuculear program"? I declined and said that I didn't want to glow green.
Ironically, my 2nd ship was the Enterprise and in place of red lights in the berthing areas in the engineering area they had green lights.
