Day 4: How to study for the ASVAB, and what score you actually need

Not necessarily. While meeting the minimum AFQT score gets you in the door, the specific job you want is determined by your line scores—composite scores from individual subtests—not just your overall AFQT. For example, a recruit with a 65 AFQT but a high Electronics line score can access better technical jobs than a recruit with a 75 AFQT and a low Electronics score. This means you need to know your target job before you study and focus on the specific subtests that determine that job's line score requirements.

Only four subtests count toward your AFQT (Armed Forces Qualification Test) score, which determines enlistment eligibility: Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, and Mathematics Knowledge. However, the other five subtests (General Science, Electronics Information, Auto & Shop Information, Mechanical Comprehension, and Assembling Objects) feed into line scores that determine which specific jobs are available to you. So while those four subtests get you enlisted, the other five can open or close career paths.

First, identify the specific line score requirement for your target job before you start studying. For technical positions, you'll likely need a strong score in Electronics Information or Mechanical Comprehension subtests. Rather than studying everything equally, focus your preparation on the subtests that directly feed into that job's line score requirement. The article notes that the Air Force recommends a 65+ AFQT for technical career fields, so aim higher than the minimum if technical roles are your goal.

Your AFQT score (calculated from just four subtests) determines whether you can enlist at all. Your line scores (composites from multiple subtests) determine which specific jobs you qualify for within your branch. The article emphasizes this is the piece most recruits miss: you could pass the ASVAB but have limited job options if your line scores don't match what you want. Knowing both scores gives you control over your career path in the military.

Significantly. According to the article, a score ten points higher can open entire career fields that are completely unavailable at a lower score. Those career fields then determine your training, deployment experience, civilian resume when you leave the military, and in many cases your re-enlistment options. This is why the article stresses that the ASVAB measures preparation, not intelligence—the effort you put in now directly controls your options for your entire military career.
