The CAT-ASVAB is an adaptive test which means the test adapts to the ability of the test-taker. It is possible to administer a shorter test this way than with the pencil and paper test. When you complete a subsection of the test, you can then move onto the next section of the test without having to wait for an administrator. Subsections are still timed however and on average it takes about 1 ½ hours to complete the computer ASVAB.
Again, we must stress that there is no passing or failing score on the exam. The test is a measure of aptitude and provides percentile rankings to indicate your performance compared to other test takers. However, different branches of the military do have minimum score requirements for enlistment. This means that it’s important to make sure you’re prepared for test day, and that’s where a practice test will prove valuable.
Many students rush to an answer without fully understanding all of the question and each of the potential answers. A good approach is to read the entire question twice before you look at the answers. Also be sure to read each of the answer choices - test writers will often put misleading answers first to lure you in. Be careful, however, not to "over-think" the question! Most of the questions on the ASVAB are straight forward and don't require a "leap of faith" to answer.
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.
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 majority of people who complete the exam have little intention of entering the military. However, it’s important to keep in mind that the United States military is actually one of the nation’s largest employers. If you’re undecided about your future after high school graduation, taking the test can give you a better picture of your options in both civilian and military life.
Paragraph Comprehension tests the ability to obtain information from written material. Students read different types of passages of varying lengths and respond to questions based on information presented in each passage. Concepts include identifying stated and reworded facts, determining a sequence of events, drawing conclusions, identifying main ideas, determining the author's purpose and tone, and identifying style and technique.
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 inverse of an exponent is the root which is indicated by a radical sign √.  A root consists of a radicand which is the number for which you’re finding the root and an index indicating which root you’re finding.  For example, in 3√8 the number 8 is the radicand and the number 3 is the root.  (A radical sign with no specified index is assumed to have an index of 2.)
The AFQT has been used in non-military settings as a proxy measure of intelligence, for example, in Herrnstein & Murray's book The Bell Curve. Because of the test's significance both inside and outside military settings, it is important to examine what the test measures, i.e. to evaluate the construct validity of the AFQT. Kaufman's 2010 review stated that David Marks (2010) scanned the literature for datasets containing test estimates for populations or groups taking both the AFQT and tests of literacy. One study on nine groups of soldiers differing in job and reading ability found a correlation of .96 between the AFQT and reading achievement (Sticht, Caylor, Kern, & Fox, 1972). Another study showed significant improvements among Black and Hispanic populations in their AFQT scores between 1980 and 1992 while Whites only showed a slight decrement (Kilburn, Hanser, & Klerman, 1998). Another study obtained reading scores for 17-year olds for those same ethnic groups and dates (Campbell et al., 2000) and found a correlation of .997 between reading scores and AFQT scores. This nearly perfect correlation was based on six pairs of data points from six independent population samples evaluated by two separate groups of investigators. According to Marks, "On the basis of the studies summarized here, there can be little doubt that the Armed Forces Qualifications Test is a measure of literacy." However, it is important to note that AFQT has been shown to correlate more highly with classic IQ tests than they do with one another, and that the "crystallized" intelligence measured by AFQT is measured very similarly by Wechsler, in particular.[8]

The way to prepare for this exam is study hard and then quiz yourself with plenty of practice ASVAB tests. Remember that the exam is identical for all branches, so an Army ASVAB practice test is exactly the same as an ASVAB practice test for the Navy. The most important components of the test are the ones that count towards the Armed Services Qualifications Test, or AFQT. These sections are Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, and Math Knowledge. For tips and strategies for success on these questions, be sure to review our article on ASVAB Test Prep.

Air Force recruits must score at least 36 points the 99-point ASVAB. The overall ASVAB score is known as the AFQT score, or Armed Forces Qualification Test score. Exceptions may be made, however, for a handful of high school graduates who can score as low as 31. The vast majority, some 70 percent, of those accepted for an Air Force enlistment achieve a score of 50 or above.
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.
If you are interested in using your test scores for military service, you will receive an Armed Forces Qualification Test (AFQT) score. This score is calculated using the scores from the Word Knowledge (WK), Paragraph Comprehension (PC), Arithmetic Reasoning (AR), and Mathematics Knowledge (MK) portions of the exam. AFQT scores are expressed as percentile scores in order to better compare results among all potential military recruits.

The AFQT score is the most important ASVAB score, because it determines if you can enlist in the U.S. Army. However, the U.S. Army also converts the ASVAB test scores into 10 other composite score areas known as "line scores" that determine what MOS an individual may qualify for. Listed below are the parts of the ASVAB that affect your AFQT test scores and each of the ten line scores.
A military recruiter determines if the candidate is a possible recruit. A recruiter will ask about marital status, health, education, drug use, and arrest record. It is important for the candidate to be upfront and truthful when answering questions. Once the recruiter has determined the individual is qualified for additional processing, the ASVAB is scheduled. A physical examination may also be conducted at the time of the test. 
The ASVAB is one of the most widely used aptitude tests in the world. The intent of the ASVAB test battery is to assess a candidate's potential for future success in the U.S. Military. Because of the nature of the test, the ASVAB can also be used to give a candidate valuable information about both military and civilian career choices that they may be suited for.

If you are pressed for time, it may be worthwhile to look into future ASVAB test dates in order to plan ahead in case you get a poor score on your upcoming ASVAB test. You can check with your high school counselor or your military recruiter to make sure that you will be eligible to take future tests along with your planned upcoming test date in the event that you get a bad ASVAB score.
A good score on the ASVAB is different than a minimum required score.  Each of the military branches will have their own minimum required scores (see below).  In practice, however, each branch will be more selective in their recruiting.  A score of 50 on the ASVAB implies that you scored as well or better than 50% of comparable test-takers.  Since ASVAB scores are used for many purposes (e.g., enlistment eligibility, military job placements, and career exploration), it is important that you score well on the ASVAB.  A score of 60 or better should be your minimum target.

The ASVAB Electronics Information subtest covers electricity principles and electronic devices, including radios, televisions, magnets, motors, transistors and much, much more.

8. Use the following passage to answer questions 8 and 9. Harry went to the drugstore and purchased band-aids, pain relievers and cold medication. He also picked up two prescriptions. He then stopped by the hardware store and bought nails, screws and a first aid kit. Finally, he went to the grocery store and bought orange juice, flour and eggs. Where did Harry buy the first aid kit?

The ASVAB was created in 1968. By 1976, all branches of the military began using this test. In 2002, the test underwent many revisions, but its main goal of gauging a person’s basic skills remained the same. Today, there is a computerized version of the test as well as a written version. The Department of Defense developed this test and it’s taken by students in thousands of schools across the country. It is also given at Military Entrance Processing Stations (MEPS).
The Auto and Shop Information subtest of the Armed Services Vocational Aptitude Battery involves questions about automobile systems and functions/malfunctions and questions about common shop tools and fasteners and their uses. Your Auto and Shop Information subtest score is used to determine various job qualifications. It is not used in determining your Armed Forces Qualification Test score. On the ASVAB for the Auto and Shop Information subtest you will have 7 minutes to answer 11 auto-related questions and 6 minutes to answer 11 shop-related questions. On the paper version of the ASVAB, you will have 11 minutes to answer 25 questions, which are usually split between auto-related questions and shop-related questions.
Many high schools give students the opportunity to take the ASVAB as part of career exploration. If you chose not to take one in high school, then you will have to schedule a time to take it. You can contact the Armed Forces Recruiting Officer in your area and you can schedule an appointment with a local recruiter from the branch of the military you wish to join.

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 Armed Forces Qualification Test (AFQT) score is derived from only four of the ASVAB subtests: Paragraph Comprehension (PC), Word Knowledge (WK), Mathematics Knowlege (MK), and Arithmetic Reasoning (AR). Your AFQT is based on a percentile system with scores ranging from 1 through 99. An average score of 50 means you score better than 50% of all other test takers. The AFQT score is by far the most important score for enlisted applicants since it determines whether you can join the military service of your choice or if you are even eligible to join the military.
Many high schools give students the opportunity to take the ASVAB as part of career exploration. If you chose not to take one in high school, then you will have to schedule a time to take it. You can contact the Armed Forces Recruiting Officer in your area and you can schedule an appointment with a local recruiter from the branch of the military you wish to join.
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.

Whenever possible, military personnel (active duty, National Guard, and reserve) will arrange to take the in-service ASVAB from your service’s Test Control Officer at a military installation; however, on a case-by-case basis, Military Entrance Processing Station (MEPS) commanders may authorize administration of an ASVAB for in-service purposes at their MEPS. You must submit a memorandum from your unit commander requesting the MEPS to administer an ASVAB. The memorandum must include;
