A minimum score of 31 is needed to get in if you have a high school diploma. If you have a GED will need a 50. The Army has been known to raise its scores up to 50 for everyone in times of high enlistments. With a high school diploma you will be good with a 35 score, with a GED you will need a 50 to enlist.
The AFQT is a grouping of sub-sections of the ASVAB and each branch has different minimums for the AFQT. For the Air Force, you have to score 36 of 99 on the AFQT. For the Army, the minimum is 31 without a waiver. For the Marines, the minimum AFQT is 32 with few waivers granted for lower scores. For the Navy the minimum is 35 and the Coast Guard is 40! I suggest you focus on getting the best ASVAB scores that you can get. Take practice tests and if you get test anxiety take tests over and over so you are familiar with it.
