Ok, you want to know how reliable the Military.com practice test is. I would say take your score, and plus or minus 10 will be your asvab score. Not too reliable. There is no harm in just going to MEPS and taking the real thing. No obligation, no swearing in and signing your life away if you just want to take the test. Just a much better way to go about things if you don't feel like going to the library. Personally, there is no way to study for it, you either know the material or you don't. I have been out of highschool for 6 years, I walked in to take the test, and it all just came back to me. Only thing I can recommend to re-look over are the geometry formulas, area of a triangle, parallelagram, cone, cylinder, all that pi and radius stuff, just to brush up on the correct formulas for each. It sucks when you have to remember that stuff and it takes a little while longer depending on how long it's been since you last had to do it.
