    Study Notes

    ASVAB General Science Practice Test

    • Test Format: 16 questions completed within 8 minutes.
    • Subject Areas: Life, Earth, and Physical Science (Biology, Geology, Meteorology, Astronomy, Chemistry, and Physics).
    • Requirements: Broad understanding of scientific principles.
    • ASVAB Arithmetic Reasoning Practice Test: 16 word problems completed within 39 minutes, testing mathematical reasoning. Examples:
      • Tire rotation: If a tire rotates 552 times in one minute, it rotates 552 * 30 = 16,560 times in half an hour.
      • Party votes: If 1 out of 9 people vote for Party A, 8 out of 9 vote for Party B. In a town of 810 people, 810 * (8/9) = 720 people vote for Party B.
      • Water flow: If 20 gallons of water come out in 5 seconds, then 20/5 = 4 gallons come out per second. In 7 seconds, 4 * 7 = 28 gallons of water come out.
    • ASVAB Word Knowledge Practice Test: 16 vocabulary questions completed within 8 minutes, assessing word understanding in context. ASVAB Vocabulary tests are an important component of your AFQT score. The test focuses on identifying synonyms.
    • ASVAB Paragraph Comprehension Practice Test: 11 questions completed within 22 minutes; tests reading comprehension skills. Includes examples of questions and answers.
    • ASVAB Mathematics Knowledge Practice Test: 16 questions completed within 20 minutes. Tests high school math knowledge.
    • ASVAB Shop Information Practice Test: 11 questions completed within 6 minutes; identifying common hand tools in a military repair shop and their uses. (New information: sample questions included)
    • Example Science Concepts Covered: Sodium chloride (salt), flaxseed (fat source), minerals (micronutrients), vitamins, blood types (A, B, AB, O), planetary order (Mercury to Neptune), mass measurement (grams, kilograms, milligrams), cloud types (cirrus, alto, stratus), vultures (scavengers), decomposers, bile (liver function), rock types (metamorphic, igneous, sedimentary), basic unit of matter (atom), nervous system (somatic, autonomic), troposphere, Newton's Laws of Motion, law of conservation of energy (energy transformation), force (mass x acceleration), mitosis, chemical elements and molecules.
    • Mathematical Concepts
      • Finding multiples: Subtracting/adding to find additional multiples.
      • Volume of a rectangular prism: Length × width × height.
      • Arithmetic mean (average): Sum of terms divided by the number of terms.
      • Solving equations: Ex. $3(x-4) = 18$ - dividing by 3 first.
      • Binomial multiplication.
      • Order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
      • Mode: Most frequent value in a dataset.
      • Slope-intercept form of a line: $y = mx + b$.
      • Exponent Rules.
      • Distributing negative signs.
      • Area of a square: Side x Side.
      • Pythagorean Theorem for right triangles.
      • Isosceles triangles: Two sides are equal.
    • ASVAB Mechanical Comprehension Example: Air pressure at X is less than air pressure at Y. Air pressure at Z is less than air pressure at X. Air pressure at X is greater than air pressure at Y. Air pressure at Y is greater than air pressure at Z.
    • Spark Plug Voltage in City Driving: Lower voltage should be applied to spark plugs in city driving because the heat from the spark is insufficient to burn off excess carbon.
    • ASVAB Paragraph Comprehension Examples:
      • East Texas differs from the western image of the state.
      • Titanium's oxide layer allows for color changes in art.
      • The deception in the passage is the warm sun despite approaching storm clouds.
      • Orientating large expanses of glass facing south optimizes solar energy.
