Practive ASVAB, and possible change of MOS?

I just took the Practice ASVAB at the Recruiter's Office and I scored a 79, which they seemed to think was pretty good. They told me that I'd most like get Mid to High-80's when I took the actual ASVAB.. which I'm taking on Thursday at 8:30 AM. Too early for me, but I should get used to it. I didn't practice for the Practice, and don't plan to for the real one. Hopefully I'll do a lot better.

My RO, Sergeant Locklear was telling me that 25B is pretty hard to get into, because there's normally a large wait list for it, and introduced me to Sergeant Whatever-his-name-was that was a 25F. He was telling me 25B is basically a Help Desk type job, and 25F is more Hardware based. I know I've read before that some RO's like to try and get some recruits to switch their MOS to one they like better, but I think 25F might be better, plus the wait list would be substantially shorter. It's still up in the air. I was also given this huge packet of questions, 31 pages long, but only have to fill out about 15 pages. All about me, high school, friends, places I've lived, family, jobs, etc. It's like a normal application for a job, only it goes in-depth on the questions. I'm having trouble remembering my old manager's name, and I don't think I ever knew who my manager was at Western Wats, but it's understandable because I only worked their for 2 weeks.

I think I found a suitable track to run on that isn't located at a school. It's about 4800 Ft. long, but it's not oval, it's kinda like a rounded rectangle so I'll check it out tomorrow. I need to buy some shorts first, and maybe some cheap running shoes at Wal-Mart; World Industries skater shoes don't work well for running track.
