 OAR Test Prep: Master the Skills & Strategies Of Maths
The OAR test is a key component of the application process for U.S. Navy officer candidates, particularly for those applying for positions in the Naval Aviator or Naval Flight Officer programs. It assesses your ability in several areas such as mechanical reasoning, mathematics, reading comprehension, and spatial awareness. Scoring well on the OAR is crucial, as it can influence your chances of being selected.

Mathematics Knowledge

The mathematics section tests your ability to solve problems related to algebra, arithmetic, geometry, and word problems.

Key Topics to Review: 

Arithmetic Operations: Addition, subtraction, multiplication, division, and operations with fractions, decimals, and percentages.

Remember the order of operations: Parentheses, Exponents, Multiplication/Division

Example: 8 + 3 × (5 − 2) = ?  Ans: 17

5 + 2² × 4 = ?  Ans: 21

Converting between decimals, fractions, and percentages.

Convert 0.75 to a fraction and percentage.

0.75 is the same as 75100\frac{75}{100}.
Simplify the fraction by dividing both the numerator and denominator by 25:
75÷25100÷25=34\frac{75 \div 25}{100 \div 25} = \frac{3}{4}.
So, 0.75 as a fraction is 34\frac{3}{4}.

What is 20% of 150?

Ans: 30

Understanding ratios, proportions, and how to solve them.

If a recipe calls for a 2:3 ratio of sugar to flour, how much sugar is needed for 6 cups of flour?

To find how much sugar is needed for 6 cups of flour, you can set up a proportion based on the ratio:

23=x6​

Where xx represents the amount of sugar needed. To solve for xx, cross-multiply:

2×6=3×x2 \times 6 = 3 \times x
12=3x

Now, divide both sides by 3:

x=123=4

So, you would need 4 cups of sugar for 6 cups of flour.
