The bow was manufactured in increasingly larger and more powerful versions, to increase both the weapon range, and armour penetration performance.

Using the right ASVAB study guide is an important factor in determining how well you will do on the exam. Each branch of the U.S. Military requires you take an ASVAB (Armed Services Vocational Aptitude Battery) exam.  Your scores on the ASVAB determine not only your entrance into the military, but also your job, advancement opportunities, and potential salary.  The ASVAB exam consists of questions in ten different areas, but in general, the exam is measuring your aptitude in four key areas: Math, Verbal, Science and Technical, and Spatial.  To efficiently prepare for your ASVAB exam, check out our recommended study guides, our free practice exams, our ASVAB flash cards, and our ASVAB study tips.


Additionally, many ASVAB practice tests have a section explaining the answer choices. It can be tempting to read the explanation and think that you now have a good understanding of the concept. However, an explanation likely only covers part of the question’s broader context. Even if the explanation makes sense, go back and investigate every concept related to the question until you’re positive you have a thorough understanding.

Standard Scores are scores that have a fixed mean and standard deviation in the population of examinees. A Standard Score indicates how many units of the standard deviation a particular score is above or below the mean. In the case of the ASVAB subtests, the mean is set to 50 and the standard deviation is set to 10. Thus, a Standard Score of 40 indicates that the examinee scored 1 standard deviation below the mean. A Standard Score of 70 indicates that the examinee scored 2 standard deviations above the mean. To learn more about how standard scores are derived and used, click here.
