Does the Practice ASVAB actually mean anything? I scored an 88 and couldn't believe how basic the test was. When I asked the recruiter how the actual ASVAB compared, he told me people usually score higher on it, and mentioned something about the actual test including questions about basic mechanics and electrical stuff. The thing is, I know nothing about those two things.

So how much of the practice test actually matters? Is practice ASVAB just there to complement and entice me to join the Air Force?

This test really threw me through a loop. I don't feel like you can really judge whether or not I'm able to become a cryptologic linguist based on this practice test, which, when compared to the real thing, is actually lower than what you would score.

Now, I understand that the military won't just look at the score of the ASVAB and say, "This guy's got the stuff," and immediately throw someone into a significant role, but as someone walking into the recruitment center and being told that I'll be able to do any job on the list, it just seems set up.

Say that I've got a specific job in mind that I'd like to do because of how much I scored on the practice ASVAB, then the day comes when I take the real thing and for whatever reason I end up just not doing too well on it. I am now stuck in the Air Force and having to change plans, most likely doing a job that I had no interest in.

I kinda rambled on, and I'm sorry about that. I'm just worried about the possibility that this practice test isn't giving me an accurate picture of what my options are in the Air Force. I really don't want to pursue something just to find out that I'm not going to be able to do that something, stuck doing something I don't want to do for four years.

Thanks if you stuck with this. Responses either answering or criticizing me are appreciated.

TL;DR: How accurately does the Practice ASVAB portray the actual test and possibility of jobs in the Air Force?
