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.
Ecology is the study of interactions between organisms and their environment. Regions that share a similar climate and soil type (and, therefore, similar animal and plant life) are called biomes and house a community of species that each belong to a population.  This combination of biome and community make up an ecosystem that consists of predators that utilize other living organisms as food, prey that becomes food to predators, and parasites that lives in or on another organism and takes nutrients from its host.

Don’t be fooled by the appearance of the low numbers, the algorithm that computes the AFQT is very sophisticated. Just because your ASVAB score is 40 doesn’t mean that you only got 40% of the questions correct, it could simply mean that you lack strength in one area, but succeed with high praise in another. Your ASVAB score is only a means by which you are categorized for available positions; it is by no means a measure of intelligence.
After the final ability estimate is computed, it is converted to a standard score on the ASVAB score scale that has been statistically linked to the ability estimate through a process called equating. Equating studies are conducted for every paper and pencil ASVAB form to ensure that scores have the same meaning regardless of which test form the examinee receives.
Education Requirements – Recruits without a high school diploma are practically ineligible to enlist. The Marine Corps do not allow more than 5% of recruits to enlist without a high school diploma, and those recruits must have a GED. Those with only a GED must score at least a 50 on the AFQT to be considered. As with the other branches, the Marine Corps provides advanced enlistment rank for recruits that have some college experience (i.e. credits). However, the Marines are less generous to recruits with some college credit as they only allow the maximum advanced rank of E-2 upon enlistment.
The SAT requires training of the mind. More specifically it requires one to be able to pick up on context clues, make valid assumptions, and express concrete facts. This is why millions of students study intensely before they jump right into the test. Imagine if another area was added onto that same test. The person studying for that test would then need to study even harder. That is the logic that should be put forth when preparing for the ASVAB. It requires that a person expresses the previously mentioned skills while adding the verbal/physical aspects. The question becomes “How does one prepare themselves for this rigorous test?”
The ASVAB Career Exploration Program provides tools developed by the Department of Defense (DoD) to help high school and post-secondary students across the nation learn more about career exploration and planning. Since the mid-1990’s, the ASVAB Career Exploration Program has provided high quality, cost-free career exploration and planning materials and services annually to approximately 14,000 of the nation’s high schools. You can prepare by taking ASVAB Practice Tests – many of which are available online.

Examinees also receive a score on what is called the Armed Forces Qualification Test (AFQT). AFQT scores are computed using the Standard Scores from four ASVAB subtests: Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Paragraph Comprehension (PC), and Word Knowledge (WK). AFQT scores are reported as percentiles between 1-99. An AFQT percentile score indicates the percentage of examinees in a reference group that scored at or below that particular score. For current AFQT scores, the reference group is a sample of 18 to 23 year old youth who took the ASVAB as part of a national norming study conducted in 1997. Thus, an AFQT score of 90 indicates that the examinee scored as well as or better than 90% of the nationally-representative sample of 18 to 23 year old youth. An AFQT score of 50 indicates that the examinee scored as well as or better than 50% of the nationally-representative sample.
Circles have a radius which measures the length from the center of the circle to any point on its curve.  The diameter is the length, through the center, from one point on the curve to another and equals radius x 2.  The circumference is the length around the curve and is equal to 2 x pi x radius (2πr) or pi times diameter (πd).  The area of a circle is pi times radius squared (πr2).

AFQT scores are reported as percentiles between 1-99. An AFQT percentile score indicates the percentage of examinees in a reference group that scored at or below that particular score. For current AFQT scores, the reference group is a sample of 18 to 23 year old youth who took the ASVAB as part of a national study conducted in 1997. Thus, an AFQT score of 95 indicates that the examinee scored as well as or better than 95% of the nationally-representative sample of 18 to 23 year olds. An AFQT score of 60 indicates that the examinee scored as well as or better than 60% of the nationally-representative sample.
An inductor stores energy in the form of a magnetic field and inductance is the property of a component that opposes the change in current of an AC circuit.  An inductor is often formed by wrapping a wire coil around a magnetic core and the level of inductance is directly proportional to the number of turns in the coil, its radius, and the type of material in the core.
Mathematics Knowledge. This section measures one's knowledge of mathematical principles and concepts. Arithmetic, geometry, and high school level algebra will comprise most of the problems. Knowing how to factor, solve, and simplify algebraic expressions; understanding exponents, absolute values, and systems of equations and solving inequalities will be helpful. You will also encounter words problems. Test takers should know how to solve word problems by creating algebraic equations. See product recommendations for more advice.
AFQT scores are reported as percentiles between 1 and 99, and the score is relative: Your AFQT score indicates how well you did compared to the scores of a reference group. For example, if you score 71, that means you scored as well as or better than 71 percent of those in the reference group. If you score 50, your score is exactly average compared to the reference group. According to the Army, about half the population scores at or above 50, and about 16 percent of the population scores at or above 60.

You should note that the exam is given only in English. This is because all of the documents you will need to reference during your military career are in English. Even if English is not your native language, you should be able to make the cut as long as you study enough. You may need to take another test, the ECL (English Comprehension Level), to make sure that you can read and follow instructions given English if it is not your native language.

The Armed Services Vocational Aptitude Battery (ASVAB) is a test that covers basic knowledge such as math and verbal skills, writing skills, and vocabulary. It is a required test for entrance into the military, but it can also be an indicator for general aptitude skills for other purposes. For those looking to go into military service, the ASVAB score is a crucial indicator of prospective job placement, so it is very important to take this test seriously and to focus on your strengths when taking the exam. Higher test scores often mean better jobs, higher salary, and more opportunities for advancement in the military.
Mathematics Knowledge tests the ability to solve problems by applying knowledge of mathematical concepts and applications. The problems focus on concepts and algorithms, and involve number theory, numeration, algebraic operations and equations, geometry, measurement and probability. Mathematics Knowledge is one factor that characterizes mathematics comprehension; it also assesses logical thinking.
Line Scores are composed of the sum of particular combinations of ASVAB subtests. These scores are used to determine if enlisted applicants are qualified to be trained in a specific military occupation. A type of line score, known as the General-Technical score, is used to determine if prospective officer candidates are qualified to join a specific branch of the military and be enrolled in officer training. Line Scores are not used to determine eligibility for particular military occupations for officer candidates. Job availability for officer candidates is based on their performance in Officer Candidate School (OCS).

The Auto and Shop Information section of the ASVAB test measures your knowledge of automobile technology and basic repairs. The shop questions are about basic wood and metals. For example, you will encounter questions such as “Shock absorbers on a car connect the axle to the: wheel, chassis, drive shaft, or exhaust pipe?” You may be asked what sanding blocks are used for, followed by the following choices: preventing high spots and ridges on sanded surfaces, preventing dirt from collecting on the sandpaper, stretching the length of sandpaper, or prolonging the use of the sandpaper. The CAT-ASVAB test has two parts: the first part covering automotive material asks 11 questions in 7 minutes; the 11 shop information questions are allotted 6 minutes. The paper-and-pencil version asks 25 questions in 11 minutes.
My recruiter told me about this book so I ordered it and got it 3 days later from the Military Bookstore. I got this book and it is awesome. The cd works great and every thing I needed and more to help me was in there. I recommend this book to everyone who is thinking of going in the service and wants to get a real job! GET THIS BOOK AND SCORE HIGH!!!!”
Barron's ASVAB is our 2nd overall prep book on our list of the best practice books. One strong point of Barron's is that the theory review and explanations are very detail-oriented and thorough. This thoroughness really helps you to absorb everything that you need to know for the exam. Learning from your mistakes is crucial, and this review guide really allows you to do just that.
Understanding the latest test-taking strategies is essential to preparing you for what you will expect on the exam. A test taker has to not only understand the material that is being covered on the test, but also must be familiar with the strategies that are necessary to properly utilize the time provided and get through the test without making any avoidable errors. Test Prep Books has drilled down the top test-taking tips for you to know.
The Student ASVAB is the most flexible of the exams. It is typically provided to high school students to help them assess their skills, job prospects, potential military positions, or college majors. The ASVAB for students is essentially the same as the MET ASVAB exam, only students are not necessarily testing for positions within the military. The students’ school counselors examine their scores and help them decide on what to do after graduating from high school. This test is still an important component of a student’s education because it can help them identify their strengths and weaknesses and help set them on the right track for their future career goals.

As part of your ASVAB prep you should get a good ASVAB study guide. Having the right study material can make a huge difference in your final score. There are a lot of ASVAB books to choose from, and some of them aren’t very good. We have reviewed all of the best study guides and our list includes only the best of the best. These are the highest-rated review books that have stood the test of time. You won’t go wrong with any of these options. These are the ASVAB study guides that we recommend:
One main shortcoming of this preparation guide is that there are some errors and misprints in the question and answer section. It may be confusing when you think that you got an answer correct but the answer section says that you got it incorrect. This sometimes wastes your time because you go through the question multiple times but then in the end you figure out that you were right all along, but were confused because of the wrong answer given.  Although with this one imperfection, Kaplan ASVAB Premier has many strengths that make it our best value and best overall pick on our list of the top rated prep guides.
The exam is not a “pass or fail” test. Your score in each area reflects your own unique abilities. Of course, you will want to study with the aim of doing your best so that you can qualify for a job that fits your skills and career interests. Your AFQT score is compared to the scores of other recruits in the 18-23 year age bracket to see how your potential measures up.
The ASVAB is a timed test. Each of the sections has a specific time limit. You need to understand the time limit, and develop a time "budget" to help you keep pace. For example, if the time limit for a section is 24 minutes, and there are 12 questions, then your time budget is 2 minutes. In this case, you should not spend more than 2 minutes per question.
PiCAT testing does require a shorter “verification test” for new recruits. This is in the form of a short, proctored test that lasts about a half an hour. Depending on circumstances, recruits may be required to take this verification test at a Military Entrance Processing Station, or within 30 days of taking PiCAT if the recruit is not going to MEPS right away. Those who do not pass the verification test will be required to take the ASVAB.
Every concept explanation is immediately followed by the practice problems. This really helps you a lot in checking and backtracking your weak points since you can go back and forth between the questions and the subjects. You can practice and review at the same time, a great time saver. It also helps you to be able to go back into the chapter and look up where you were wrong. Make sure to reread the section if you are missing a lot of questions in certain sections. This makes it easy to see what your secret weaknesses are.
For the Air Force, Army, Marine Corps, and Navy a retest will only be authorized if a recruit's test scores expire, their scores are too low, if the recruiter feels your scores do not match your qualifications, or in the event of special circumstances that bar a recruit from taking the test. A retest will not be authorized to simply increase an already successful score in order to qualify for particular occupations or for enlistment bonuses. Usually, recruits with successful scores holding a job reservation or who are enrolled in the Delay Entry Program (DEP) are not eligible to retest.
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.
Taking the PiCAT exam may, depending on circumstances including scores and other factors, may relieve a new recruit of having to take the ASVAB in a proctored setting. In the past, recruits who were preparing to enter military service at Military Entrance Processing Station would take the ASVAB in a group setting; PiCAT can help new recruits avoid having to retake the test. PiCAT test performance and other factors will determine whether or not the ASVAB has to be taken at MEPS.
After the final ability estimate is computed, it is converted to a standard score on the ASVAB score scale that has been statistically linked to the ability estimate through a process called equating. Equating studies are conducted for every paper and pencil ASVAB form to ensure that scores have the same meaning regardless of which test form the examinee receives.

The military has used the Armed Services Vocational Aptitude Battery (ASVAB) for the last 40 years to place soldiers into careers and to determine whether or not a soldier could follow directions and be trained. The military says the ASVAB is a useful measure of future academic and occupational success in the military -- if a solider can read it. Testers must understand the ASVAB’s long list of abbreviations if the test itself is to be used to its best advantage.
Improper Fraction: With an improper fraction, the numerator is bigger than the denominator. To convert a mixed fraction to an improper fraction multiply the denominator by the whole integer part, then add this to the numerator. This is the new numerator of the converted improper fraction. The original denominator is retained. For example, with , multiply 5 by 1, and add this product to 3 to get:
It had sections on the mechanical portion of the ASVAB that were very helpful as well as Mathematical practices that served as a great refresher for me. The strategies were also very helpful and gave me confidence going into the test. After going through the book and taking the practice exams, I feel I was well prepared for the ASVAB test. My score almost doubled from my previous attempt at the test after using this guide.
The CAT version of the test is timed and takes about an hour and a half. This version is the one given most frequently to military recruits. The MET test is a pen-and-paper version, and is more suitable to recruits who may need to take more time and go at their own pace. A referral from a recruiter is required for the MET test; when you complete your test your results are sent to the recruiter, who verifies them and helps you assess your scores. 
Students are given a Standard Score for each of the subtests. Standard Scores are derived from your Raw Scores (total number of points you receive on each subtest). The Standard Scores are a statistically derived score that typically ranges from 30 and 70 for each subtest. The Standard Scores are created such that a 50 represents a mean (average) score and there is a standard deviation of 10 (implying that 95% of test takers are within two standard deviations, 20 pts, of the mean of 50).
McGraw-Hill’s ASVAB, 3rd Edition: Strategies + 4 Practice Tests. A final option is this ASVAB study guide from McGraw-Hill. The author of this book used to work for the Department of Defense in their ASVAB career program, so she definitely has the inside track on test prep. Includes comprehensive topic reviews, four complete practice tests, and test-taking strategies. And remember, you will take the same test whether you are planning to join the Army, Navy, Air Force, Marine Corps, or Coast Guard.
Reading page after page of boring content can cause the strongest minds to wander. Taking practice tests are a great way to break up the monotony of studying. Taking a practice test challenges you and keeps you interested in the material. Then you can review your test results and go over the questions you got wrong committing the right answer to memory. It’s a great, streamlined way to learn.
This advice, though well-intentioned, doesn’t address the needs of some new recruits who are interested in specific career fields but are worried about their test performance-especially in areas related to math comprehension. Potential recruits who feel deficient in math, language, or science skills should have a frank conversation with their recruiter to discuss possible refresher study or even supplemental classes in any self-perceived “problem areas” before taking the test.
If you are interested in joining the military then the Armed Services Vocational Aptitude Battery (ASVAB) may, very well be, the most important test you'll ever have to take. Spanning everything from job selection and pay grade to serving in the branch of your choice or even serving at all, the importance of the ASVAB cannot be overstated. The primary function of the ASVAB is to determine if recruits are qualified for service, and if they possess the skills necessary for receiving training in a variety of military occupations.

After adopting the test in 1976 the test became a way of indicating whether or not an individual was 100% qualified to serve. As previously mentioned this aptitude test has a colorful history. That is because it underwent a dramatic change in 2002 and another dramatic change in 2004. The change that occurred in 2002 expanded the categories of the test and the overall difficulty. This can be seen by the addition of all of the diverse categories below:
