Do u think i have a good chance of ping the asvab?

Ok so back in 2007(when they accepted GEDs only) I took a practice test at the recruiters office(sgt. bullock) and scored at 26 i believe, he told me that the real asvab is easier so he was positive that was going to score at least a 31%(ARMY) but i didnt, i made a 25....but towards halfway thru the test, I start guessing anything, I didnt even bother looking at the questions, I thought I would automaticially p because I heard it was like a 5th graders test, so I didnt take it seriously...The recruiter told me to study and I did a tiny bit, took it again and did worst, I got a 23, but again I start guessing on answers towards the end. Fast forward to 2010 and I REALLy want to join, but I got stopped in my tracks because I needed 15 college credits, and I have 6 right now, I will be obtaining the last 9 credits in spring semester...but I hear you can enlist in the DEP or future soldier program if u already have your cl schedule and I do, already paid for the cles and everything. So I met a recruiter and he's really cool and young..I took a practice test and scored a 51, he said to brush up on my word knowledge(I did horrible on that subject) and I should at least get a 60 but my score of 51 is good too. he said that i can take the asvab on monday and i agreed... So since then i been studying the dictionary, having conversations with friends with good vocab ad asking them what the words mean. But I'm reallly nervous....I have the asvab for dummies 2nd edition and 3rd edition and I studied my off, took countless practice test...I'm so nervous about it that I had dreams about it, I can't really focus on things like work and stuff because the asvab test....I'm a cashier at a retail store and I have my asvab book underr the counter so when I don't have customers, i pull it out and study it.(my boss doesn't mind) am I stressing too much? Do u think that I can p it and I'm just thinking too hard on it??....stress can be bad and hurt your chances so im trying to relax about it but I can't help it, as soon as i make it home, i dive my head into books without even having dinner..should i stop studying and just wait for monday and take it?
