Year.Pdf
The ASVAB (Armed Services Vocational Aptitude Battery) is a multiple-aptitude test
used by all U.S. military branches to assess applicants' suitability for enlistment and job
qualification . It is not a pass/fail exam but measures developed abilities across academic
and technical domains . The Armed Forces Qualification Test (AFQT) score, derived from
four subtests, is the most important number for determining enlistment eligibility .

ASVAB)
CAT-ASVAB: Approximately 145 questions, 154 minutes total
P&P-ASVAB: Approximately 225 questions, 149 minutes total
Question Count Note: The exact number varies slightly by test version; 170
practice questions are provided here for comprehensive preparation.
CORE DOMAINS COVERED (10 Subtests)
1. General Science (GS) – Life, earth, space, and physical sciences
2. Arithmetic Reasoning (AR) – Math word problems
3. Word Knowledge (WK) – Synonyms and vocabulary
4. Paragraph Comprehension (PC) – Reading comprehension
5. Mathematics Knowledge (MK) – Algebra, geometry, and math concepts
6. Electronics Information (EI) – Electrical principles and circuitry
, 7. Auto Information (AI) – Automotive maintenance and repair
8. Shop Information (SI) – Tools and shop practices
9. Mechanical Comprehension (MC) – Mechanical and physical principles
10. Assembling Objects (AO) – Spatial visualization
SECTION ONE: GENERAL SCIENCE (GS) – Questions 1-17
1. The process by which plants convert sunlight, water, and carbon dioxide into
glucose and oxygen is called what?
A) Respiration
B) Photosynthesis
C) Fermentation
D) Transpiration
Rationale: Photosynthesis is the biological process where plants use chlorophyll, sunlight,
carbon dioxide, and water to produce glucose (energy) and oxygen as a byproduct .
2. In the human circulatory system, which type of blood vessel carries oxygen-
depleted blood back to the heart?
A) Arteries
B) Capillaries
C) Veins
D) Arterioles
Rationale: Veins carry deoxygenated blood back to the heart (with the exception of the
pulmonary veins). Arteries carry oxygen-rich blood away from the heart .
3. Earth's atmosphere is primarily composed of which two gases?
A) Oxygen and Carbon Dioxide
B) Nitrogen and Oxygen
, C) Hydrogen and Helium
D) Nitrogen and Argon
Rationale: Earth's atmosphere is about 78% nitrogen and 21% oxygen, making these the
two most abundant gases .
4. The chemical formula for table salt is:
A) H₂O
B) CO₂
C) NaCl
D) HCl
Rationale: NaCl (sodium chloride) is the chemical formula for table salt, formed by the ionic
bond between sodium and chlorine .
5. Which organ system is responsible for filtering waste products from the blood and
producing urine?
A) Digestive System
B) Respiratory System
C) Endocrine System
D) Urinary System
Rationale: The urinary system, including the kidneys, ureters, bladder, and urethra, filters
blood and removes waste as urine .
6. The freezing point of water on the Celsius scale is:
A) 32°C
B) 100°C
C) 0°C
D) 212°C
, Rationale: Water freezes at 0°C (32°F) and boils at 100°C (212°F) .
7. Which organelle is known as the "powerhouse of the cell" because it produces
energy?
A) Nucleus
B) Ribosome
C) Mitochondria
D) Golgi Apparatus
Rationale: Mitochondria are responsible for cellular respiration and ATP production,
providing energy for the cell .
8. The solid, outermost layer of Earth, including the crust and upper mantle, is called
the:
A) Core
B) Asthenosphere
C) Lithosphere
D) Hydrosphere
Rationale: The lithosphere is the rigid outer layer of Earth, composed of the crust and the
uppermost part of the mantle .
9. Which of the following is an example of a vertebrate?
A) Spider
B) Snail
C) Frog
D) Clam
Rationale: Frogs are vertebrates (have a backbone). Spiders, snails, and clams are
invertebrates .
