The CAT-ASVAB delivers 145 adaptive questions across 10 subtests in roughly 1.5-2 hours at MEPS. The AFQT (Armed Forces Qualification Test) is calculated from WK + PC + AR + MK. Minimum AFQT scores: Army 31, Marines 31, Navy 31, Air Force 36, Coast Guard 40. Unlike the paper P&P-ASVAB (225 questions, fixed order), the CAT-ASVAB raises or lowers difficulty after each item. The exam is FREE; scores are valid for 2 years.

1Which organ is primarily responsible for filtering nitrogenous waste from human blood?
A.Liver
B.Kidney
C.Spleen
D.Pancreas
Explanation: The kidneys filter nitrogenous waste (such as urea) from the bloodstream and produce urine. The liver detoxifies many substances but converts ammonia to urea — the kidneys then excrete it.
2Photosynthesis converts carbon dioxide and water into glucose and what other product?
A.Nitrogen
B.Oxygen
C.Methane
D.Hydrogen sulfide
Explanation: Photosynthesis: 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2. Oxygen is released as a byproduct when plants split water molecules.
3Which subatomic particle carries no electrical charge?
A.Proton
B.Electron
C.Neutron
D.Positron
Explanation: Neutrons are electrically neutral. Protons carry +1 charge, electrons carry -1, and positrons carry +1.
4What is the SI unit of force?
A.Joule
B.Newton
C.Watt
D.Pascal
Explanation: Force is measured in newtons (N), where 1 N = 1 kg·m/s^2. Joules measure energy, watts measure power, and pascals measure pressure.
5Which layer of Earth lies directly beneath the crust?
A.Outer core
B.Inner core
C.Mantle
D.Lithosphere
Explanation: Earth's structure from outside in: crust -> mantle -> outer core -> inner core. The mantle is mostly solid silicate rock that flows slowly over geologic time.
6An object's mass on the Moon compared with its mass on Earth is:
A.About one-sixth as much
B.The same
C.About six times greater
D.Zero
Explanation: Mass is an intrinsic property and does not change with location. Weight (mass x gravitational acceleration) is about one-sixth on the Moon because lunar gravity is roughly 1/6 of Earth's.
7Which blood vessels carry blood away from the heart?
A.Veins
B.Capillaries
C.Arteries
D.Venules
Explanation: Arteries carry blood away from the heart. Veins return blood to the heart. Capillaries are the microscopic exchange vessels between arteries and veins.
8Water's chemical formula H2O indicates how many hydrogen atoms per molecule?
A.1
B.2
C.3
D.4
Explanation: H2O has two hydrogen atoms and one oxygen atom. The subscript 2 denotes two hydrogen atoms.
9Which gas makes up the largest percentage of Earth's atmosphere?
A.Oxygen
B.Carbon dioxide
C.Nitrogen
D.Argon
Explanation: Nitrogen comprises about 78% of the atmosphere, oxygen about 21%, argon about 0.9%, and carbon dioxide about 0.04%.
10Which process changes a liquid directly into a gas?
A.Sublimation
B.Vaporization
C.Condensation
D.Deposition
Explanation: Vaporization (including boiling and evaporation) is liquid -> gas. Sublimation is solid -> gas; condensation is gas -> liquid; deposition is gas -> solid.

About the CAT-ASVAB Exam

The CAT-ASVAB is the computer adaptive version of the ASVAB administered at Military Entrance Processing Stations (MEPS). The test serves 145 questions across 10 subtests, with item difficulty adjusting to each examinee's running ability estimate. AFQT scores (derived from WK, PC, AR, and MK) determine enlistment eligibility, while line scores determine MOS qualification.

CAT-ASVAB Study Tips from Top Performers

1Answer the first items of each subtest carefully — early correct answers raise difficulty (and ceiling) faster
2Practice mental math — no calculator is allowed on any ASVAB version
3Verbal Expression (WK + PC) is weighted DOUBLE in the AFQT formula; prioritize vocabulary
4Pace yourself: running out of time on adaptive subtests is penalized, so do not stall on one item
5Study basic Ohm's law and series/parallel circuits for Electronics Information

Frequently Asked Questions

What is the CAT-ASVAB?

The CAT-ASVAB is the Computer Adaptive Test version of the ASVAB administered at MEPS. It serves 145 questions across 10 subtests in approximately 1.5-2 hours. Each subtest is adaptive: harder questions follow correct answers and easier questions follow incorrect ones, so test length is shorter than the paper version while measuring the same constructs.

How is CAT-ASVAB different from paper ASVAB?

The CAT-ASVAB has 145 questions and adapts difficulty in real time, while the paper-and-pencil ASVAB (P&P-ASVAB) has 225 fixed questions. CAT-ASVAB also splits Auto Information (AI) and Shop Information (SI) into separate subtests, whereas the paper version combines them into a single Auto & Shop section. Both produce equivalent AFQT scores.

What AFQT score do I need on the CAT-ASVAB?

Minimum AFQT scores by branch: Army 31, Marines 31, Navy 31, Air Force 36, Space Force 36, Coast Guard 40. Higher scores qualify you for more jobs — AFQT 50+ opens most career fields. The AFQT is calculated from four subtests: WK + PC + AR + MK.

Can I skip questions or go back on the CAT-ASVAB?

No. Because the CAT-ASVAB adapts to your responses, you cannot skip a question or return to a previous item once you submit. Answer carefully — guessing late in a subtest can be penalized if you run out of time without completing items.

Where is the CAT-ASVAB administered?

The CAT-ASVAB is delivered at Military Entrance Processing Stations (MEPS) on DoD-managed computers. The paper P&P-ASVAB is used at Mobile Examining Test (MET) sites for applicants who cannot travel to a MEPS facility.
