The Armed Services Vocational Aptitude Battery (ASVAB) is a test administered to three potentially separate groups of people: interested high school students, individuals who are looking to enter the military, and military service members who are looking to reclassify and retrain into a job that requires higher test scores.
So, if you are looking to take the ASVAB and want to get the best score possible, or if you have taken the ASVAB and are not really happy with your score, you can be one of the people who significantly improve your score. How? This article will provide you with practical tips on how to study for the ASVAB, where to focus your efforts, and how to use practice tests and structured study resources to get you test-day ready and get the ASVAB score you want.
How is the ASVAB structured?
The ASVAB tests your knowledge of basic concepts and skills and produces two types of scores: the Armed Forces Qualification Test (AFQT) score, which helps determine enlistment eligibility, and composite scores (also called line scores), which helps determine the specific jobs you qualify for.
The ASVAB provides you with several scores shown as percentiles:
- AFQT score
- Standardized Scores (Subtest Scores)
- Composite Scores (Line Scores)
AFQT
Your AFQT score comes from answers to questions in four core sections:
- Arithmetic Reasoning (AR)
- Word Knowledge (WK)
- Paragraph Comprehension (PC)
- Mathematics Knowledge (MK)
Note: PC and WK are combined to determine a scaled Verbal Expression (VE) score.
Here is how your AFQT is calculated: 2 x WK + PC + (AR + MK) = AFQT Raw Score
Your raw score is turned into a percentage that tells you how well you did compared to other test takers, and is shown as a percentile from 1 to 99, where 50 is the national average. It does not mean you answered a specific percentage of questions correctly.
In general, a good AFQT score is between 50 and 64. This demonstrates a solid understanding of the ASVAB sections. Scores of 65 and above are considered excellent and open up many more job opportunities, especially in specialized, technical programs.
Standardized Scores (Subtest Scores)
Standard scores are given for each of the nine sections of the ASVAB. Here are the sections and their commonly referred to abbreviations:
|
Subtest |
Description |
|---|---|
|
General Science (GS) |
Knowledge of physical and biological sciences |
|
Arithmetic Reasoning (AR) |
Ability to solve arithmetic word problems |
|
Word Knowledge (WK) |
Ability to select the correct meaning of words presented in context and to identify the best synonym for a given word |
|
Paragraph Comprehension (PC) |
Ability to obtain information from written passages |
|
Math Knowledge (MK) |
Knowledge of high school mathematics principles |
|
Electronics Information (EI) |
Knowledge of electricity and electronics |
|
Auto and Shop Information (AS) |
Knowledge of automobile technology, tools, and shop terminology and practices |
|
Mechanical Comprehension (MC) |
Knowledge of mechanical and physical principles |
|
Assembling Objects (AO) |
Ability to determine how an object will look when its parts are put together |
Your score is based on a scale where 50 is the national average and your score represents how above or below the average you are. In other words, it is based on how many questions you answered correctly compared with others who have taken the test.
Your standard scores alone don’t determine anything specific, but they are used to calculate your composite scores, or line score, which determine your eligibility for jobs in each branch of the military.
Composite Scores (Line Score)
Composite scores, also called line scores, help determine which military job is right for you, and some composite scores are required for certain jobs and branches. This is part of the classification process, which matches new recruits to specific jobs and branches where they may perform well in.
According to the official ASVAB website, “Each service develops and validates its own set of composites based on the combination of subtests that are most highly correlated with on-the-job performance for clusters of occupations.”
Understanding how ASVAB scoring works and what your ASVAB scores mean, helps you study strategically and focus on the sections that matter most. Overall, knowing how your ASVAB scores apply to your potential enlistment, position, and rank will make the testing process much less confusing and more productive.
For example, if you are looking to join the Air Force and want a career as a Cyber Systems Operations Specialist, you will need a minimum line score in two categories, Electronics (60) and Mechanical (45).
Electronics (E) is a score based on a composite of the following subtests:
- Arithmetic Reasoning (AR)
- Electronics Information (EI)
- General Science (GS)
- Mathematics Knowledge (MK)
Mechanical (M) is based on these subtests:
- Arithmetic Reasoning (AR)
- Auto & Shop Information (AS)
- Mechanical Comprehension (MC)
- Paragraph Comprehension (PC)
- Word Knowledge (WK)
Pro Tip: If you have a specific military job in mind, make sure to know what standardized subtest scores make up the line score for that job. You can see what required line scores for each military job in these articles:

Build a 30-Day Study Plan
One of the biggest mistakes you can make is to study without a plan. You will either take random practice tests to gauge your readiness, or buy a prep book and start at page one, getting burned out halfway through. A good approach is to build a solid 30-day study plan, putting focus on areas that will both give you the best chance for a good score on the AFQT and subtests that will determine your line scores.
Overview
Study the four core areas (AFQT subtests) first, because they determine your AFQT score.
- Arithmetic Reasoning (AR)
- Word Knowledge (WK)
- Paragraph Comprehension (PC)
- Mathematics Knowledge (MK)
Then build a solid study plan, beginning with which branch and jobs you are interested in, and then finding out which line scores you need.
These technical subsets will help determine your line score, and in turn, which special job you qualify for. Focus on the subtests that make up your desired line score:
- General science (GS)
- Electronics information (EI)
- Auto and shop information (AS)
- Mechanical comprehension (MC)
- Assembling objects (AO)
30 Day Study Plan
Aim for at least two hours of dedicated study per day, and keep notes of areas you need to review, such as formulas, vocabulary, and weak areas.
Week 1: Diagnostics and Verbal Knowledge (WK and PC)
- Day 1: Take a baseline untimed practice test (without looking up answers) and record your scores. Highlight your weak areas for each section.
- Day 2: Analyze the Results (every missed question and why you missed it)
- Days 3–4: Word Knowledge (study roots and prefixes)
- Days 5–7: Paragraph Comprehension (practice reading short paragraphs for main ideas)
Week 2: Math Fundamentals (AR and MK)
- Day 8: Practice math basics like long division, and fractions.
- Day 9: Arithmetic Reasoning (Word Problems)
- Day 10: Mathematics Knowledge (Algebra & Geometry)
- Days 11–12: Geometry shortcuts (memorize common formulas)
- Days 13–14: Do math questions with no calculator (time yourself)
Week 3: Technical Subtests (GS, MC, EI, AS, and AO)
Prioritize your focus, spending more time on technical subtests that directly determine your line score that determines your job qualifications (MOS/AFSC/Rating).
- Day 15: General Science
- Day 16: Mechanical Comprehension
- Day 17: Electronics Information
- Day 18: Auto and Shop Information
- Day 19: Assembling Objects
- Day 20–21: Take practice quizzes on technical areas (especially those focused on areas based on preferred job line scores)
Week 4: Timed Exams and Wrap Up
Focus on skills you will need on test day such as time management and testing endurance.
- Day 22: Full-length timed practice exam (simulate test day)
- Day 23: Review results and fine-tune errors
- Day 24: Target weaknesses by focusing on two lowest subtests
- Day 25: AFQT intensives (timed practice exam just on WK, PC, AR, and MK)
- Day 26: Technical review intensives (final push on areas based on your preferred job line score).
- Day 27: Final practice test (focus on pacing to get through exam)
- Day 28: Review of personal notes
- Day 29: Rest (don’t cram and get plenty of sleep)
- Day 30: Test Day (trust your plan!)

Most Common ASVAB Mistakes
If you have read through our list of tips and study strategies and follow our 30-day study guide, you should be able to avoid the following common ASVAB mistakes:
- Ignoring your weaknesses: Challenge yourself on harder subjects
- Studying without a plan: Create and keep to a schedule, like the 30-day plan we outlined.
- Not using realistic practice resources: Take computerized practice tests to simulate test day.
- Memorizing without understanding: Understand the reason behind the formulas so you can’t be tripped up.
- Wrong math calculations: Focus on the step-by-step calculations so you don’t add when you should multiply.
- Rushing through math word problems: Thoroughly read the question (without dwelling too long) to understand the logic behind the question.
- Answering too soon: Read the entire question before answering to avoid missing clues at the end of the text.
- Running out of time: Pace yourself using the timing benchmarks you’ve built through repeated practice sessio
Test-Day Strategies
Since the CAT-ASVAB (Computer Adaptive Test) is the most widely used version of the test, and is the version administered at Military Entrance Processing Stations (MEPS), we will focus on test-day strategies for the CAT version.
General Strategies
- Eat a high-protein low-carb breakfast.
- Arrive early and relax.
- Read each question carefully before picking your answer.
- Know what the question is asking before looking at the answers.
- Read all answer options before selecting one.
- Don’t answer based on the frequency of previous answers. Answers are randomized, so there may be 5 “C” answers in a row.
Time Management Tips
- If you are stuck on a question, guess by eliminating clearly wrong answers. There are no penalties for wrong answers. The next question gets harder or easier based on whether you got the last one right.
- Spend no more than 30 seconds on easier questions and one minute on harder ones.
ASVAB Retest Rules
One of the most asked questions about the ASVAB is “Can I retake the ASVAB?” The short answer is, yes. According to the official ASVAB website, you can retake the ASVAB as many times as you wish; however, there are time requirements after you take each test.
To take the ASVAB a second time, there is a one month waiting period. If you want to take it any additional times, you must wait six months between tests. Remember, only the latest test counts, so if you receive a lower score than on a previous test, that is your current official ASVAB test score.
If your AFQT increases by 20 or more points within six months, you will have to take a confirmation test (C-Test) to verify the retest score gain. You don’t have to wait one month before taking the C-Test, you can take it immediately.
Key Takeaways
- AFQT (AR, WK, PC, MK) determines enlistment; composite line scores from subtests determine job eligibility.
- Follow a 30-day plan: 2 hrs/day, AFQT first (WK, PC, AR, MK), then technical subtests, then timed full exams.
- Use official timed practice, pace yourself, guess when stuck (no penalty). Retest: 1 month, then 6 months.
FAQ
How is the AFQT score calculated?
Your AFQT score is based on four ASVAB subtests: Arithmetic Reasoning (AR), Word Knowledge (WK), Paragraph Comprehension (PC), and Mathematics Knowledge (MK). The raw score formula is: 2 × WK + PC + (AR + MK), which is then converted into a percentile from 1–99 showing how you performed compared to other test-takers.
What is considered a good ASVAB AFQT score?
A score between 50 and 64 reflects strong understanding of core ASVAB subjects. A score above 65 is excellent, and opens more technical job opportunities across the military branches.
What are line scores, and why do they matter?
Line scores (composite scores) determine which military jobs (MOS/AFSC/Rating) you qualify for. Each branch uses different combinations of subtests to calculate these scores.
Can I retake the ASVAB if I’m not happy with my score?
Yes. You must wait 30 days before your second attempt and 6 months between any additional attempts.
How do I know which ASVAB subtests matter for my desired military job?
