Sure it wasn't 99.9? It's not expressed as a percentage. And generally, only the GT score is used. (At least when I was in. It has changed.) Mine was 126.
Raw score. 99.9. I never heard of the GT score. I went in back in '78. I know I took the thing seven times and got 99.9 every time. That's what I was shown by my recruiter and my SDI. I scored in the 99.9 percentile of everyone who had ever taken the ASVAB.
The Navy wanted me to go into the Nuke program.
In the sixth grade I was reading at a 16th grade level with 99% comprehension and retention.
When I received the score from the test in my senior year of high school I decided it was time to talk to the recruiter. The federal building was on the way home. I walked in and down the hall to the Marine recruiting office. When I walked in the recruiter was on the phone and told me he would be right with me.
He had one of his card file drawers open. There was one card standing on end in it. When he got off the phone he asked what he could do for me. I told him my name and he turned around and grabbed that one card that was standing on end. He then told me he would be right with me. He walked into the hall, closed the door and yelled "He's in my office". The next thing I see is all the other recruiters standing on the other side of that glass wall looking in.
Gunnery Sgt. Comier gave me a ride home that day. Before I got in the door the other recruiters were there wanting to talk to my parents.
