Initially, recruits without higher education or college degrees will hold the pay grade of E-1 and will be elevated to E-2 usually soon after basic training. Different services have different incentive programs for enlistees, such as higher initial ranks for college credit, being an Eagle Scout and referring friends who go on to enlist as well. Participation in DEP is one way recruits can achieve rank before their departure to basic training.
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.
These are sections, or sub-tests, in the ASVAB:  Word Knowledge (WK), Paragraph Comprehension (PC), Arithmetic Reasoning (AR), Mathematics Knowledge (MK), General Science (GS), Mechanical Comprehension (MC), Electronics Information (EI), and Assembling Objects (AO), Auto & Shop Information (AS):  * AI and SI are administered as separate tests in the CAT-ASVAB (computerized version), but combined into one single score (labeled AS).
Word Knowledge (WK), Paragraph Comprehension (PC), Mathematics Knowledge (MK), Electronics Information (EI), Auto & Shop Information (AS), and Mechanical Comprehension (MC). These subtests focus on basic knowledge of science, math, writing and vocabulary, an understanding of structural development and mechanics, auto function and repair, and a knowledge of electric currents, electronic systems, and circuits. These are all skills and knowledge that are necessary for different sectors of military service. Scores in each subtest are based on the student’s ability to answer the questions correctly and to complete the test in time to answer as many of the questions as possible.
If you are enlisting in the military, good - a patriotic journey, where you can build skills and see the world. However there is one thing your recruiter didn't tell you. Your ability to get into a department that you want, depends on how well you can take a quiz - just like you did with the SAT, or whatever those test are called in current times. Those test asked those really stupid questions about the cost of ice cream if a train leaves New York at 4:00 and it is 20 degrees on Colorado. This book will teach you how to answer those ridiculous questions that WILL control your destiny. Get a copy and memorize it... then serving your country will lead to a great career.
The Armed Forces Qualification Test (AFQT) is used by all of the Services to determine if an applicant is eligible for the military. Four of the ASVAB subtests are combined to form the AFQT. It measures general cognitive ability and is composed of verbal and mathematics subtests. AFQT scores are grouped into categories for reporting purposes. The table below shows the AFQT categories and the percentile score ranges corresponding to the categories. Applicants that score in AFQT category IIIA or higher may qualify for enlistment incentives.
