burned out

im back to trying to enlist in the military one last time. i have been studying a bit in order to take my asvab and i just cant seem to push myself to study any further. i plan on taking the test this Wed. i dont need my score to be very high. as im just trying for combat infantry maybe airborne if its available. but i hope i do better than the 45 i got on the practice test i took a month or so ago. my recruiter said he wants me to get at least a 50 or better in order to see me get the best chance of a career i want. so we will see....
