How to improve your AFQT score
Your AFQT comes from four ASVAB subtests: Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge and Paragraph Comprehension. To improve it, find which of those skills you miss most, fix them with short daily practice and error review, and learn how the computer test handles answers and time before you sit it.
What makes up your AFQT score?
Four subtests: Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Paragraph Comprehension (PC) and Word Knowledge (WK). The official scores page says AFQT scores are "computed using the Standard Scores" from those four (Official ASVAB: Understanding ASVAB Scores). The official FAQ adds that the ASVAB is one exam with 10 tests and that the AFQT is the score made from four of them (Official ASVAB applicant FAQs).
The official pages checked do not publish a weighting formula on their applicant score page, so this guide does not give one. What matters for studying is that all four count, and that math is two of the four.
Your AFQT is a percentile. An AFQT of 50 means you scored as well as or better than 50% of the reference group, a nationally representative sample of 18 to 23 year olds from a 1997 norming study (Official ASVAB: Understanding ASVAB Scores). Because it is a comparison with that group, there is no fixed number of right answers that equals a given AFQT. The AFQT score explainer and how the AFQT is calculated go into more detail.
Which AFQT subtest should you work on first?
Start with the subtest where a diagnostic shows the most misses that you can fix quickly. Usually that is AR setup errors or a specific MK rule, because both respond fast to practice.
- Take the 20-item math practice test and verbal practice test with no calculator.
- Count misses and guesses for each of the four subtests.
- For each miss, write the cause: misread, setup, missing rule or arithmetic slip.
- Pick the subtest with the most fixable misses. A missing rule (such as exponent rules) or a repeated setup error is fixable in days. A large vocabulary gap takes weeks.
Keep some practice on all four even while you focus on one. The free skill check also samples all four subjects and points to the lesson for your weakest one.
How do you raise your Arithmetic Reasoning score?
Fix your setup. Most AR misses come from solving the wrong question or building the wrong relationship, not from the arithmetic itself.
- Write the target in a few words before you compute ("total cost after tax").
- Find the unit rate or the relationship (per hour, per gallon, percent of what).
- Keep units in your work, and convert them before you combine numbers.
- Check the size: does the answer make sense for the story?
Example: A tank holds 120 gallons and is 3/8 full. How many gallons are needed to fill it?
- Target: gallons still needed, not gallons in the tank.
- The tank is 3/8 full, so 5/8 is empty.
- 5/8 of 120: 120 / 8 = 15, and 15 x 5 = 75.
- Check: 3/8 of 120 is 45, and 45 + 75 = 120.
Answer: 75 gallons
Then study the common types one at a time: word problem types, distance and rate, interest and percent change and averages.
How do you raise your Mathematics Knowledge score?
Learn the rules that MK tests most often and practice them until they are automatic. MK covers "high school mathematics principles" (Official ASVAB: ASVAB Subtests), so it rewards knowing rules more than clever reasoning.
- Equations and inequalities: do the same thing to both sides, and flip the inequality sign when you multiply or divide by a negative. See algebra.
- Exponents and roots: add exponents when multiplying the same base, and simplify roots by pulling out perfect squares. See exponents and roots.
- Geometry: area, perimeter, circle formulas, angle sums and the Pythagorean theorem. See the geometry review and formula list.
- Fractions and signs: most MK slips are sign errors and fraction mistakes. See fractions.
Write each formula from memory once a day for a week, then check it. Retrieval practice like this is more reliable than rereading a formula sheet.
How do you raise your Word Knowledge and Paragraph Comprehension scores?
For WK, learn words in sentences and use word parts. For PC, practice proving every answer from the passage.
WK measures choosing the meaning of words "presented in context" and the best synonym (Official ASVAB: ASVAB Subtests). Build a small card deck of 10 new words a day, each with a short definition and your own sentence, and review old cards before adding new ones. Learn common roots and prefixes from the word roots guide, since one root can unlock several words.
PC measures the ability to obtain information from written passages (Official ASVAB: ASVAB Subtests). Before choosing an answer, find the sentence that supports it. If you cannot point to one, the choice is likely an assumption. The PC strategies guide and the evidence lesson show the method. Reading something real for 10 minutes a day helps both subtests.
What kind of practice actually improves a score?
Short, regular sessions with error review beat long cramming sessions. A practical routine has four parts.
- Retrieval. Answer questions and recall formulas or word meanings from memory, rather than rereading notes.
- Spacing. Revisit a topic a day later, a few days later and a week later.
- Error review. Keep a log of misses with their causes, and redo each one from a blank page a few days later. The review lesson shows how.
- Test-like conditions. Work without a calculator, commit to each answer in order and time some sets.
The 30-day plan and the one-week plan put this routine on a calendar. The official preparation page also recommends taking sample questions and reviewing the content areas where you need to freshen up (Official ASVAB: Preparing for the ASVAB).
How do you track whether your AFQT prep is working?
Track the things you can measure on your own: how many logged mistakes you can now solve, how accurate you are on fresh sets and how long a set takes.
| What to track | How | How often |
|---|---|---|
| Error log items solved | Redo each logged miss from a blank page; cross off the ones you now get right | Weekly |
| Accuracy by subtest | Count right answers on fresh AR, MK, WK and PC sets separately | Twice a week |
| Speed | Time a 10-item set and compare with the official average time per question | Weekly, once accuracy is steady |
| Vocabulary | Count cards you recall correctly three times in a row | Weekly |
Keep these numbers in one notebook. When one stops moving for two weeks, change the approach for that skill: a new lesson, a different kind of practice or more spaced review.
Do not turn these numbers into an AFQT estimate. The AFQT is a percentile against a national reference group (Official ASVAB: Understanding ASVAB Scores). The official AFQT Predictor Test is the recruiter's tool for an estimate, and its own page says the prediction is "not a guarantee" (Official ASVAB: The AFQT Predictor Test (APT)).
How do test strategies affect your AFQT?
Strategy cannot replace skill, but poor strategy can cost points you earned. Know the official rules for your version of the test.
- On the CAT-ASVAB you cannot return to a question once you answer it (Official ASVAB: Preparing for the ASVAB), so commit carefully.
- Unfinished CAT-ASVAB items are scored as though answered at random (Official ASVAB: The CAT-ASVAB), and the official advice when time runs short is to legitimately answer rather than guess randomly (Official ASVAB: Preparing for the ASVAB).
- On the paper version, answer every question; there is no penalty for guessing (Official ASVAB: Preparing for the ASVAB).
The test-taking strategies guide covers both versions in detail.
What are the rules for retaking the ASVAB to raise your AFQT?
You must wait between attempts. The official retest policy requires a one-month wait between the initial test and the first retest, another one-month wait before a second retest, and six months between any additional retests (Official ASVAB: Retest Policy).
If your AFQT rises by 20 or more points within six months, the official policy calls it a critical gain and requires a Confirmation Test (C-Test) to verify it (Official ASVAB: Retest Policy). The policy also says the C-Test can be taken right away, without the usual one-month wait.
The GoArmy page says the Army uses your most recent score, not your highest (GoArmy.com: ASVAB test and preparation). Its retake answer also describes the timing differently from the official retest policy, so confirm with your recruiter before you plan a retest. GoArmy also describes a Future Soldier Preparatory Course with an academic track for applicants with a minimum score of 21 (GoArmy.com: ASVAB test and preparation). See retake rules for more.
Scores can be used for enlistment for up to two years from the test date (Official ASVAB applicant FAQs).
Use the waiting period well. Start the week after your test with the subtest you felt least sure about, rebuild your error log from memory while the test is fresh, and follow the 30-day plan so the next attempt is backed by a month of steady practice.
Practice questions
Work each one on paper first, then open the explanation. These are original AptiStep items, not real ASVAB questions.
A tank holds 120 gallons and is 3/8 full. How many more gallons are needed to fill it?
- 45 gallons
- 75 gallons
- 80 gallons
- 40 gallons
Show answer and explanation
Answer: B. 75 gallons
The tank is 3/8 full, so 1 - 3/8 = 5/8 of it is empty. 120 / 8 = 15 gallons per eighth, and 15 x 5 = 75 gallons. Check: the tank already has 15 x 3 = 45 gallons, and 45 + 75 = 120. 45 is the amount already in the tank, which answers a different question.
Simplify: 3(2x - 5) - 4x.
- 2x - 5
- 10x - 15
- 2x - 15
- 2x + 15
Show answer and explanation
Answer: C. 2x - 15
Step 1: distribute the 3 to both terms: 3 x 2x = 6x and 3 x (-5) = -15, giving 6x - 15. Step 2: combine like terms: 6x - 4x = 2x. The result is 2x - 15. Check with x = 1: 3(2 - 5) - 4 = -9 - 4 = -13, and 2(1) - 15 = -13. Distributing only to the first term gives 2x - 5.
Concur most nearly means:
- agree
- compete
- argue
- finish
Show answer and explanation
Answer: A. agree
Concur means to agree or share the same opinion, as in "the doctors concur that rest is needed." The prefix con- means together or with, which fits agreeing with someone. Compete and argue suggest disagreement, the opposite idea, and finish is a different meaning altogether.
On a map, 1 inch represents 25 miles. Two towns are 3.5 inches apart on the map. How far apart are they in miles?
- 75 miles
- 28.5 miles
- 100 miles
- 87.5 miles
Show answer and explanation
Answer: D. 87.5 miles
Multiply the map distance by the scale. 3 inches is 3 x 25 = 75 miles, and half an inch is 12.5 miles, so 3.5 inches is 75 + 12.5 = 87.5 miles. 75 drops the half inch, 100 rounds up to 4 inches, and 28.5 adds the numbers instead of multiplying.
Most home fires that start in the kitchen begin while someone is cooking. The fire department recommends staying in the kitchen while frying or broiling food and keeping towels and paper away from the stove. If a small grease fire starts in a pan, sliding a lid over the pan cuts off its air. Water should never be thrown on a grease fire, because it can spread the burning oil.
According to the passage, why should water never be thrown on a grease fire?
- It can spread the burning oil
- It makes the pan too hot to touch
- It wastes water the fire department needs
- It cuts off the fire's air
Show answer and explanation
Answer: A. It can spread the burning oil
The last sentence says water should never be thrown on a grease fire "because it can spread the burning oil." Cutting off air is what the passage says a lid does, so that choice describes the recommended method, not the danger. The other choices are not mentioned.
Frequently asked questions
Which subtest matters most for the AFQT?
The official scores page names AR, MK, PC and WK as the four AFQT subtests without publishing a weighting on that page (scores page). Work on all four, starting with your weakest.
How long does it take to improve an AFQT score?
It depends on your starting point and how much you practice. No one can promise a number of points. Fixing specific, repeated mistakes is the most reliable way to make progress in a few weeks.
Do the other ASVAB subtests affect my AFQT?
No. Only AR, MK, PC and WK go into the AFQT. The other subtests feed job composites, called line scores by the Army; see line scores.
Can AptiStep tell me my AFQT?
No. AptiStep is an independent practice app and site for the four AFQT subjects. It does not predict AFQT percentiles. The official AFQT comes only from the ASVAB itself.
