A wheel and axle can be thought of as a flexible lever that rotates around a center point that acts as the fulcrum. The arm lengths are represented by the radius of the wheel upon which the load force is applied and the radius upon which the load is applied. Depending upon which wheels the load and resistance forces are applied, the wheel and axle can multiply force or multiply speed.

There are different minimum AFQT score requirements for enlisting in the Army, Navy, Marines, Air Force, and Coast Guard, although requirements will vary depending upon whether you have a high school diploma or a GED. Minimum score requirements change on a fairly regular basis, with higher scores being required during times of above-average enlistment levels. Enlistment bonuses, which are determined by your choice of military occupation, may also be influenced by AFQT scores.

There is another ASVAB score that's equally important, if not more so, because it is the score that determines if a person is eligible for military service. It's the Armed Forces Qualification Test score, or AFQT score. This score is calculated from only four of the nine Standard Scores on the ASVAB - Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Paragraph Comprehension (PC), and Word Knowledge (WK). First, the WK and PC scores are added together, then the sum is doubled. This is known as the Verbal Expression (VE) score. The VE, MK, and AR scores are then added together, and the sum is the AFQT. This score is a straight percentile measure, expressed as a number from 1-99. The number is the percentage of people who scored lower than the test taker. For example, if a person receives an AFQT score of 63, that means that he did better on the test than 63% of the people who have taken it.

Retesting is possible depending on a variety of circumstances. It is possible to retake the ASVAB or PiCAT, but you will need to coordinate this with your recruiting office. In general you may be required to wait a month or more to retake the test; each branch of the service may have different requirements that must be fulfilled in order to retest.
The military offers boundless opportunities for people looking for a career in serving their country. The five branches of the military (Army, Navy, Marine Corps, Air Force, and Coast Guard) all have active, reserve, and guard units with jobs unique to each branch and level of commitment. Examples of different jobs include military police, telephone technician, psychological operations specialist, journalist, dental specialist, and oboe player. Each job allows for different levels of advancement depending on factors such as job performance and length of service.
The Arithmetic Reasoning section of the ASVAB test focuses on word problems and delivers mathematical questions and equations in a format that must be synthesized. These may not only be simple questions involving basic multiplication, but may also be as complex as completing a physics equation listed in paragraph or word-block format. When deconstructing these word problems, pay close attention to all aspects of the question, including all numbers mentioned, buzzwords, and the format of the paragraph itself. The following pointers will give you a more in-depth analysis of each component of word problems.

You can't use the AR and MK score shown on your ASVAB Score Sheet. The Score Sheet shows "number correct" for your AR and MK Scores, because "number correct" is what is used for job qualifications. However, the military does not use this same score when computing the AFQT. They use the "weighted scores" of the ASVAB sub-tests for AR and MK. Harder questions in these areas get more points than easier questions. The "weighted scores" for AR and WK are not listed on the ASVAB score sheet given to you after the test.


As you go along, keep in mind that the ASVAB practice test is just that: practice. Memorizing these questions and answers will not be very helpful on the actual test because it is unlikely to have any of the same exact questions. If you only know the right answers to the sample questions, you won’t be prepared for the real thing. Study the concepts until you understand them fully, and then you’ll be able to answer any question that shows up on the test.

Cells replicate by mitosis in which a cell duplicates its chromosomes and then splits in two resulting in both cells receiving a set of chromosomes that perfectly matches the parent cell or through meiosis which reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

The Armed Services Vocational Aptitude Battery is more commonly known as the ASVAB Test. If you are interested in a military career, you will need to pass this challenging test in order to qualify. It is used for all branches of the military which includes the Army, Navy, Air Force, Marines, National Guard, and Coast Guard. It is also used to gauge your abilities in specific areas that may be relevant to your job assignments within the military. For more information about the exact details of this exam, check out our article titled What is the ASVAB Test?

Understanding ASVAB scores is critical if you want to enlist in the U.S. Military and get the military career of your dreams. The ASVAB test is an aptitude test but is not a perfect measure of your knowledge, skills and abilities. Your scores do not guarantee whether you will be successful in a future occupation. Your ASVAB scores, however, need to be good enough to get you into the military branch of your choice.


For applicants with a high school diploma, the minimum required AFQT score to enlist in the Coast Guard is 40, while GED applicants must score a 50. GED recruits make up only 5 percent of each year's Coast Guard class. If an applicant's ASVAB subtest scores qualify for a specific job that is in demand, use of a waiver is possible if the applicant agrees to enlist for that job.
The ASVAB contains 10 subtests, which are grouped under different qualification areas. The AFQT portion of the test includes Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, and Arithmetic Reasoning subtests. A minimum score of 32 on this portion is required to enlist in the Marine Corp for recruits with a high school diploma, and those with a GED must score 50.
The Mathematics Knowledge section of the exam measures your knowledge of various math areas, such as algebra and geometry. You may be asked to find the square root of a number or the volume of a brick with given dimensions. Algebraic problems may require finding the value of “y” in a given equation. A review of math symbols—such as ≠, ≤, and √—can help you solve the given problems much faster, and using our ASVAB math study guide to practice answering the algebra and geometry questions on the test can help increase your overall AFQT score. The CAT-ASVAB has 16 questions in 20 minutes; the paper-and-pencil version has 25 questions in 24 minutes.
Below you will find a helpful list of several official full length tests, sample questions, and guides to aid you in your studying for the ASVAB. It is important to remember while these resources may be helpful, they are not exhaustive in detail and will not cover everything found on the test. These guides should be used to familiarize yourself with the content and format of the questions. Click the links below to begin reviewing sample questions and taking your practice tests.
There are essentially two options when it comes to preparing for this test. First, a person can attempt to reassess all of the information that they learned over a decade by spending hours compiling information. Secondly, a person can find a specially formatted ASVAB practice test that covers all areas of both the written test and computerized test. Clearly, the best choice is the ASVAB practice test. The question becomes “Where does one find an accurate ASVAB practice test?”
