Guaranteed Success On OAR Test Prep

 Unlock Your Potential: OAR Test Prep Made Easy for 100% Success

Preparing for the Officer Aptitude Rating (OAR) test, which is part of the selection process for the U.S. Navy's Officer Candidate School (OCS) or other military officer programs, requires a structured and effective approach. The OAR test evaluates your aptitude in several areas such as math, reading comprehension, and mechanical comprehension. To achieve a high score and increase your chances of success,

Understand the OAR Test Structure

Mathematical Skills: This includes basic arithmetic, algebra, and word problems. You'll need to be comfortable with solving equations, understanding fractions, percentages, and basic number theory.

Area of a Triangle:

$$A = \frac{1}{2} \times \text{base} \times \text{height}$$

This formula calculates the area of a triangle given its base and height.

The average of a set of numbers is the sum of the numbers divided by the number of items: $$\text{Average} = \frac{\text{Sum of terms}}{\text{Number of terms}}$$

The ASVAB (Armed Services Vocational Aptitude Battery) math test evaluates arithmetic reasoning and mathematical knowledge. Here are some important formulas to remember for the math sections of the ASVAB:

Arithmetic and Number Operations Formulas

1. Percentages:

   • To find a percentage of a number: $$\text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100$$
   • To find the part when you know the percentage: $$\text{Part} = \left(\frac{\text{Percentage}}{100}\right) \times \text{Whole}$$
   • To find the whole when you know the part and percentage: $$\text{Whole} = \frac{\text{Part}}{\text{Percentage}} \times 100$$

2. Fractions:

• Adding/Subtracting Fractions:
  To add or subtract fractions, they must have the same denominator. $$\frac{a}{c} + \frac{b}{c} = \frac{a + b}{c}$$
• Multiplying Fractions: $$\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}$$
• Dividing Fractions:
  Multiply by the reciprocal of the divisor: $$\frac{a}{b}÷\frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$$

1. Decimal to Fraction Conversion: 

   • To convert a decimal to a fraction, place the decimal number over the appropriate power of 10. For example, $0.75 = \frac{75}{100} = \frac{3}{4}$.

2. Average:

   • The average of a set of numbers is the sum of the numbers divided by the number of items: $$\text{Average} = \frac{\text{Sum of terms}}{\text{Number of terms}}$$

3. Ratios:

   • A ratio compares two quantities. For example, if the ratio of boys to girls in a class is 3:4, it means for every 3 boys, there are 4 girls.

4. Proportions:

   • A proportion is an equation stating that two ratios are equal. $$\frac{a}{b} = \frac{c}{d}$$
   • To solve a proportion, cross-multiply: $$a \times d = b \times c$$
