over a year later but i'm doing this mostly for people needing it now or in the future.
The A.S.V.A.B will usually come to your high school at the end of the year maybe mid second semester and will cover the basics of mechanics, English / comprehension and algebraic mathematics i would recommend setting aside a few days of the month to study so that you can hit it hard the day it comes
you're going to want over a 35 or a 40 to qualify for basic service max score is a 99 if you're a nuclear scientist alot of people don't score well on it the first time that's why you get two opportunity's one on your junior year and one on your senior
But if you're happy with your score the first time I recommend not to take it again as the newest score you get is the one you keep its not like the act
wake up early in the morning, eat a full breakfast, maybe do a little exercises, and come it with a screwtop energy drink these will make you as ready as you can get.
