How to Pass the Electronics Information Test

Not sure how to pass the Electronics Information test? The Electronics Information subtest of the ASVAB exam is frequently needed for many of the most sought-after positions in the US military. Scoring high on the test doesn’t need to be difficult. Here, we explain why.

To score high on any subtest of the ASVAB test, you must know the syllabus. Not having the syllabus to hand is the equivalent of trying to navigate across the Atlantic Ocean without a map. Knowing the syllabus means you can create a long-term study plan that caters to the needs of each topic. It means making a plan that incorporates revision schedules; and it also means taking the time to put together the tools and resources you need to study each aspect of that syllabus.

We already discussed the syllabus in our Electronics Information study guide. Here, you can see what’s included:

Syllabus SubjectTopics
Measuring ElectricityVolts
Electrical PrinciplesTypes of resistance
Ohm’s law
Electrical effects
Direction of electrical flow
CircuitsAlternating current
Direct Current
Electrical circuit symbols
Types of switches

With this knowledge to hand, you can put together a plan that works to help you pass the electronics information test.

But even if electronics information is not your strongest subject, it doesn’t mean you need to find the exam difficult, either.

Concepts to Keep in Mind

Often, it’s common sense we need to apply.

When confronted with an electronics information question, try to think through the problem for yourself. Often, very obviously false answers are included. Take an ASVAB test practice question where you are asked, “Which of these is the safest practice when changing fire alarms?”. If one of the answers refers to “…leaving the live wire exposed”, you can be sure that this answer is false. To select that answer is to tell the examiner that you are willing to increase the risk of electrocution.

Aside from thinking through the problem and choosing the most reasonable and logical answer, there are other techniques you can apply.

First, you should know the basics about the Electronics Information test. Sometimes, this is enough to figure out the correct answer.

Here are just some of the core details of the syllabus that you are expected to know:

ResistanceOhms (symbol: Ω)
CurrentAmperes (amps)

Ohm’s Law

current, voltage, resistance


power, voltage, and amperes


  • Current always flows from negative to positive.
  • Electricity can only flow in a closed circuit (no open gaps).
  • A transistor is a type of semiconductor device used to amplify or switch electronic signals and electronic power.
  • The Hertz is the unit of measurement of frequency.
  • Rectifiers are devices that change alternating current to direct current.
  • Standard electronic devices operate at high frequencies.

Of course, you must also be familiar with electrical circuits.

There are several dozen symbols to memorize. You should be able to correctly identify symbols from circuits, as well as understand the function of each of these symbols.

One of the best ways to achieve this is with ASVAB flashcards. Place an electrical circuit symbol on one side of the card, and the explanation on the opposite side. By routinely revising these cards, you will memorize these symbols in no time.

Take Home Message

Electronics Information is a highly competitive subtest on the ASVAB exam.

Given the low number of places and the high demand for those places, only the best scoring candidates will make it through to achieve the target MOS or line score for their target position in the military.

That said, the exam doesn’t need to be difficult. All that it requires is a structured approach to your study. Here, we have outlined the base upon which you must build further. By knowing the core information that always gets tested, you can add layers of additional understanding in the weeks to come – covering more of the syllabus that we have outlined above.

As always, the best way to prepare for the ASVAB test is to utilize as many effective study tools as possible. This means using flashcards, realistic practice test questions, and learning from the best ASVAB study guides around. Taking a rounded approach that covers all aspects of the syllabus is what’s required.

By incorporating these tips into your study plan there is no reason why you cannot ace the Electronics Information subtest.
