The ASVAB also known as the Armed Services Vocational Aptitude Battery is a test that measures your aptitude which is how well you do something.  A common mistake by most people is thinking that it is a measure of you IQ. Many people either forget this or don’t know this and they get worked up about the exam.  Saying that, it is also important to take a ASVAB sample test to insure you know what type of questions will be asked.    Another thing to keep in mind is every person in the armed forces has to take the exam and you are not being called out to take it. 
Tenga en cuenta que los MEPS es operado por los militares, por lo que no tiene mucho sentido del humor cuando se trata de los códigos de vestimenta. Vestir de manera conservadora. No use ropa con agujeros en ellos o malas palabras escritas en ellas. Asegúrese de que su ropa interior no se muestra. Dejar su sombrero en casa porque, bajo el código de vestimenta civil y militar, no se puede usar sombreros en interiores.
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.
To be admitted to the ASVAB testing room you will need to show a valid id. It is also important to be on time (or early!) since you will be turned away if you show up after the scheduled start time. The ASVAB can be given via computer or pencil and paper.  If you are testing at a MEPS site you will take it on a computer.  The pencil and paper version is given at most MET sites.  The computer version of the test is given as a "computer adaptive test" (CAT) which means that the test will adapt based on the level of the individual test taker (e.g., if you answer many questions correctly, you may be shown fewer questions).

For those who are interested in enlisting in the military, they are screened using the Armed Forces Qualification Test (AFQT), which is comprised of a subset of scores from the ASVAB. Successfully passing the AFQT is not the sole requirement for enlisting but is one of the qualifications that must be met. There are various requirements for the different branches of the military and those interested are encouraged to contact recruiters to obtain more information about requirements specific to that branch.
The Armed Services Vocational Aptitude Battery (ASVAB) is one of the most widely used multiple-aptitude test batteries in the world. It was originally designed to predict success in military occupations and is used today to help both those considering entering the military (mostly high school-aged students, but also anyone who is eligible to enlist) as well as those not interested in military service (who comprise the majority of current ASVAB test takers) what sort of career may be the best fit for them. Scores from the ASVAB can be used when enlisting in the military. Students interested in taking the ASVAB should check with their high school to find out when and if the ASVAB will be offered at their school. If it is not offered, students should meet with their guidance counselor to determine if it is possible to schedule a testing session in the future. There is no cost to take the ASVAB.
While you may want to get the ASVAB over with, it is important to give yourself enough time to prepare and practice for the ASVAB. Once you take the test you will have to wait 30 days before you are eligible to re-take the test if you got a non-passing score, or if you want a better grade. After you retake the test twice, you will need to wait for a 6 month time period before being able to take the test again. For this reason, it is important to pick an ASVAB test date that gives you plenty of time to practice and prepare for each section of the test.
The CAT-ASVAB has a total of 145 questions with a time limit of 154 minutes. The CAT-ASVAB test questions are computer-adaptive, meaning that they either increase or decrease in difficulty level based on your responses to previous questions. The questions, therefore, are tailored to each test taker’s ability. There is a penalty for wrong answers on this exam, so guessing is not to your advantage. The time of test completion depends on your individual speed. If you finish a section before the allotted time, you can move forward to the next without waiting for the other test takers.
The adaptive test is exactly what it sounds like, a test that adapts to the test taker. Questions in each section range in difficulty, and based on the test taker’s answers, the question types and difficulties adjust with each answer. This type of test allows for a greater level of accuracy in evaluating a prospect’s abilities. For the most part, correct answers beget more difficult questions while wrong answers will reduce the difficulty of proceeding questions.
Every single individual that goes through the enlistment process should excel both mentally and physically. That is the number one principle that has consistently inspired this nation to serve these brave and honorable individuals with unwavering efforts. Those efforts officially came to the forefront when the country as a whole decided to correct perhaps the most significant enlistment related problem (passing the Armed Services Vocational Aptitude Battery test). Countless hours of hard work and dedication are currently reflected by the top-of-the-line ASVAB practice tests that this nation offers.
