What’s on the ASVAB?
First, let’s talk about the difference between the CAT-ASVAB and the P&P-ASVAB.
The P&P-ASVAB is the paper-and-pencil version of the test.
The number of questions and the time limit for the ASVAB will differ depending on which version you take. The CAT-ASVAB contains 135 questions with a 186-minute time limit, and the P&P-ASVAB contains 225 questions with a 149-minute time limit.
The AI and SI sections are administered as separate sections on the CAT-ASVAB, while the P&P-ASVAB combines them into one section (AS).
Let’s take a closer look at the contents of the ASVAB as a whole.

ASVAB vs. AFQT
People often think that the AFQT is either another name for the ASVAB or maybe an entirely separate exam that they have to take.
In reality, the ASVAB is the only exam you’ll have to take. The Armed Forces Qualification Test (AFQT) is actually a scoring system that’s used to see if you’re even eligible to enlist in the military at all.
Here’s how it works.
Before your overall ASVAB score is looked at, the scores from the Arithmetic Reasoning (AR), Math Knowledge (MK), Paragraph Comprehension (PC), and Word Knowledge (WK) sections are combined to create your AFQT score.
These sections test the basic essentials that are deemed necessary to enlist in the military. If your AFQT score is high enough, then your full performance on the ASVAB is looked at to determine which branch of the military you would be best suited for.
How the ASVAB is Scored
First, let’s look at how the AFQT score is determined.
AFQT Score
Your AFQT score is set as a percentile between 1 and 99. This means that if your AFQT score is 85, you scored as well as 85% of test-takers!
So what counts as a passing AFQT score? That depends on which branch of service you plan on joining.
If you are not satisfied with your score and want to retake the test, you’ll have to wait a month before taking it again.
You can retake the test as many times as you want, but after 3 attempts the waiting period jumps to 6 months.
ASVAB Score
Once your AFQT score is determined and is considered a passing score, your remaining ASVAB scores will be determined. Your score in each area reflects your own unique abilities, so they will affect the assignments you get after you’re enlisted.
