Check Asvab For Dummies Chapter 1 Summary
The ASVAB specifically measures your ability to be trained to do a specific job.
To develop an effective plan of study and score well on the ASVAB, it’s important to understand how the ASVAB is organized and how the military uses the scores from the subtests.
If you’re not interested in a job requiring a score on the Mechanical Comprehension subtest, you don’t need to worry about doing well on that subtest.
Spend the time on Word Knowledge or Arithmetic Reasoning.
Doing well on each subtest will broaden your available job choices and make you a more desirable candidate.
Achieving the minimum required AFQT score established by an individual branch gets your foot in the door, but the higher you score, the better.
Your ASVAB test results determine whether you qualify for military service and, if so, which jobs you qualify for.
Even so, if you’re Category IV, your chances of enlistment are small and mostly limited to the Army National Guard.
Follow this plan ensures a relatively accurate appraisal of your aptitude for various military jobs.
Knowing which kind of job you want to do in the military, the ASVAB helps you and the military determine your potential ability for different types of jobs.

Qualifying to join is only part of the picture.
Unless you’d be content to spend your military career painting things that don’t move, you need to understand how the ASVAB relates to various military job opportunities.
You’re going to go to military school to study how to make computers stand at attention and fly right.
The military spends big bucks turning high school graduates into highly trained and skilled aircraft mechanics, language specialists, and electronic-doodad repair people.
Every single Army recruit knows what his or her job is going to be before signing the enlistment contract.
Each service branch has its own system of scores.
If you get an appropriate score in the appropriate areas, you can get the job you want.
All enlistment contracts for the reserve forces contain guarantees for a specific job.
Line scores combine various standard ASVAB scores to see which jobs or training programs you qualify for.
A percentile score of 51 indicates you scored better in this aptitude area than 50 percent of the testers.

"You won’t do well on tests if you keep telling yourself that you can’t."
"Those who do well on tests are those who’ve figured out how to study efficiently and how to use a dash of test-taking psychology."
"The military has a saying, 'Train as you expect to fight.' The same is true of the ASVAB."

A decent vocabulary is essential in the military if you want to get ahead.
The more words you understand, the more ideas you can understand.
Clear communication is so important that it’s taught and graded at all levels of leadership training.
Developing a large vocabulary takes time — often years.
You don’t need to study all those words. It’s possible to decipher English word meanings, even if you’ve never heard a particular word before.
If you memorize prefixes, suffixes, and roots, you have a better chance of figuring out the meaning of an unfamiliar word.
You can acquire vocabulary words in the short term as well as over a long period of time.
Reading for enjoyment is crucial; studies show that those who read have a much larger vocabulary.
When you encounter a word you don’t know, try to understand what it means by looking at the context.
One way to improve your vocabulary is to keep a word list.

The Paragraph Comprehension subtest measures your ability to understand what you read and draw conclusions from that material.
Trust me on this one: if you can’t read and understand a regulation that’s buried within a pile of papers, how are you going to obey it?
The AFQT is the most important score.
You’d be surprised at how many diverse military jobs require a decent score on the Paragraph Comprehension subtest.
If you can identify the main point, you’re more likely to understand the whole paragraph.
The main idea, which is the most important point the author is making, is sometimes stated and sometimes implied.
Analyzing a passage requires you to draw conclusions from what you’ve read and understand relationships among the ideas.
You don’t need to enroll in a speed-reading course. If you devote at least one hour a day simply to reading, you’ll see your reading comprehension and speed increase within a month.
How do you prove to yourself that you understand what you’re reading? Here are a couple of tips.
The Paragraph Comprehension subtest tests your ability to understand what you read, not how quickly you can read it.

Check Asvab For Dummies Chapter 6 Summary
Don't sweat. This test is just for practice, and it doesn’t count for a score.
The communication subtests of the ASVAB are very important because they comprise a significant portion of your AFQT score.
To motivate your people, give them tasks that challenge them.
Get to know your people and their capabilities, so you can tell just how far to push each one.
When they succeed, praise them.
When they fall short, give them credit for what they’ve done and coach or counsel them on how to do better next time.
Organizational leaders influence several hundred to several thousand people.
Organizational leaders have staffs to help them lead their people and manage their organizations’ resources.

Arithmetic Reasoning tests how you apply your ability to perform calculations to real-life problems.
To do well on the Arithmetic Reasoning subtest, you have to remember that there are two parts: arithmetic and reasoning.
Correctly solving math word problems requires you to perform a series of organized steps.
Ask yourself whether you’ve ever seen a problem like this before.
Clue words can be a big help when trying to figure out which question is being asked.
Make sure you attach units of measurement contained in the problem.
If your solution seems improbable, you’ve probably made a mistake in your calculations.
Guessing wrong on any of the ASVAB subtests doesn’t count against you.
Eliminating answers that can’t be right increases your chances of picking the right answer.
Using a little logic, do calculations with an obviously wrong answer choice.

Scientists are pretty skeptical. They don’t necessarily believe anything said by anyone else unless it’s been shown to be true (time after time after time) using a process called the scientific method.
Instead of trying to remember nine million individual facts, spend some time reviewing the general principles behind the facts.
Thinking about how the facts relate to each other. Looking at the big picture is an effective learning technique.
