Free Marine Corps ASVAB Practice Test
Marine Corps ASVAB preparation has two jobs: help you meet the AFQT enlistment requirement and help you build the composite score connected to the MOS path you want.
Start with the four AFQT subjects, then focus on the Marine Corps composite that matters most to you: GT, EL, MM, or CL.
Marine Corps ASVAB Practice Test
A supply section receives 28 cartons. Each carton holds 16 meal packs. How many meal packs are received?
Multiply cartons by packs per carton: 28 × 16 = 448.

A cleaning solution is mixed in a ratio of 1 part concentrate to 4 parts water. How much concentrate is needed to make 25 gallons of solution?
There are 5 total parts. 25 ÷ 5 = 5 gallons per part, so the 1 concentrate part equals 5 gallons.
Solve for x: 7x + 5 = 47.
Subtract 5 to get 7x = 42, then divide by 7. x = 6.
Simplify m⁶ ÷ m².
When dividing powers with the same base, subtract exponents: 6 − 2 = 4.
What is the volume of a rectangular box that is 8 units long, 5 units wide, and 3 units high?
Volume = length × width × height = 8 × 5 × 3 = 120 cubic units.
A right triangle has legs of 9 and 12. What is the length of the hypotenuse?
9² + 12² = 81 + 144 = 225. √225 = 15.

An element's atomic number is defined by the number of protons in its nucleus.
Which type of rock forms when magma or lava cools and solidifies?
Igneous rock forms from cooled and solidified molten material.
In an experiment, the factor deliberately changed by the researcher is the:
The independent variable is the factor the researcher intentionally changes.
Which statement best explains why a metal spoon feels colder than a wooden spoon in the same room?
Metal is a better thermal conductor, so it transfers heat away from the hand faster even when both objects are at the same room temperature.
An 18-volt source is connected across a 6-ohm resistor. What current flows?
Ohm's Law: I = V ÷ R = 18 ÷ 6 = 3 amperes.
In a simple parallel circuit, the voltage across each branch is:
In a parallel circuit, each branch is connected across the same two points, so each branch has the same applied voltage.
A device operates at 12 volts and draws 4 amperes. How much electrical power does it use?
Electrical power P = V × I = 12 × 4 = 48 watts.
Which component is primarily used to store electric charge?

A ball-peen hammer is commonly used for metalworking tasks such as shaping metal and striking punches.
Which tool cuts internal threads in a drilled hole?
A tap cuts internal threads. A die cuts external threads.
Using a longer wrench to turn the same tight bolt makes the task easier mainly because the longer wrench increases:
Torque equals force times perpendicular distance from the pivot. Increasing the wrench length increases that distance.
The three external gears shown mesh in a row. If Gear A turns clockwise, which direction does Gear C turn?
Each external gear contact reverses direction. A turns clockwise, B turns counterclockwise, and C turns clockwise.
In a hydraulic system, the same fluid pressure acts on a small piston and a larger piston. Which piston can produce the greater output force?
Force equals pressure times area. At the same pressure, the larger piston area produces greater force.
A machine does 1,200 joules of work in 4 seconds. What is its power output?
Power = work ÷ time = 1,200 ÷ 4 = 300 watts.
For the lever shown, which change would reduce the effort force needed to lift the same load?
Increasing the effort-arm length increases mechanical advantage, reducing the force required to lift the same load.
Which option correctly joins point a on the first object to point b on the second object?
The correct choice connects the marked upper-right location on the first shape to the marked lower-left location on the second shape.
Which option shows the original shape after rotation rather than reflection?
The correct option preserves the shape's handedness and keeps the dot on the corresponding corner after rotation.
Which divided board best matches the three separate pieces shown when rotation is allowed?
The correct board creates regions that can match the two L-shaped pieces and the straight three-block piece without reflection.
If point x must touch point y, which option best represents the two pieces fitted together without overlapping?

HIGH-VALUE MARINE SUBTEST
Why Arithmetic Reasoning Deserves
Extra Attention
Arithmetic Reasoning contributes to AFQT and also appears in MM, GT, and EL.
Practice rates, ratios, percentages, proportions, distance, time, averages, money problems, and multi-step word problems. The key skill is often turning the words into the correct mathematical setup.
MECHANICAL COMPREHENSION
Mechanical Comprehension Matters Beyond
the Mechanical Composite
MC contributes to both MM and GT. Practice force, leverage, gears, pulley systems, pressure, friction, work, power, motion, and mechanical advantage.
For diagrams, identify what can move and where force is being applied before choosing an answer.
VERBAL EXPRESSION
Verbal Skills Can Affect Marine Technical
Qualification
Word Knowledge and Paragraph Comprehension combine into VE, which contributes to both Clerical and General Technical scoring.
Separate verbal mistakes into vocabulary gaps, missed passage evidence, weak inference, and main-idea errors.
GENERAL SCIENCE
Where General Science Matters Most
General Science contributes directly to the Electrical composite. Review biology, Earth science, chemistry basics, matter, energy, force, and motion.
If EL is your target and GS is weak, doing more circuit questions alone will not fix the full score profile.
AUTO + SHOP
Auto and Shop Information Supports
the Mechanical Composite
On CAT-ASVAB, Auto Information and Shop Information are separate subtests. For Marine Mechanical preparation, both areas deserve targeted practice.
Review engines, cooling, lubrication, brakes, drivetrain, tools, drills, cutting, fasteners, and measurement.
AO
Still an ASVAB Subtest
Assembling Objects measures spatial visualization and remains part of CAT-ASVAB.
Not in GT / EL / MM / CL
Current Composite Priority
AO does not appear in the four current Marine Corps composite formulas listed above.

Do Not Memorize Competitor or Real Test Questions
A strong Marine Corps ASVAB practice test should use original wording and new scenarios while testing the same underlying skills.
The goal is to solve unfamiliar questions correctly, not recognize one repeated question bank.
PiCAT
Eligible applicants who have never taken the ASVAB may receive PiCAT access through a recruiter. A potentially qualifying result must later be verified in a proctored setting.
Verification Matters
Do PiCAT without outside help. The later Verification Test is designed to confirm that the result represents your own ability.
