ETS HiSET scoring guide

The HiSET Mathematics subtest, developed by ETS, consists of 50 multiple-choice questions to be completed in 90 minutes. Test-takers receive a formula reference sheet and may use a calculator. Scores range from 1 to 20, with a subtest passing score of 8 and a minimum composite score of 45 (across all five subtests) required to earn the HiSET credential. The heaviest content area is Algebraic Concepts at approximately 45% of the exam, making it the single most important area to study. As of 2025–2026, the HiSET is accepted in 22 U.S. states and territories as a high school equivalency option. (Source: ETS / hiset.org)

1A store sells a jacket for $85. If the store offers a 20% discount, what is the sale price of the jacket?

A.$17.00

B.$65.00

C.$68.00

D.$72.00

Explanation: A 20% discount means you pay 80% of the original price. 80% of $85 = 0.80 × $85 = $68.00. Alternatively, 20% of $85 = $17 discount, and $85 − $17 = $68.

2What is the value of the expression 3/4 + 2/3?

A.5/7

B.5/12

C.17/12

D.1/2

Explanation: To add fractions, find a common denominator. LCD of 4 and 3 is 12. 3/4 = 9/12 and 2/3 = 8/12. So 9/12 + 8/12 = 17/12.

3A recipe calls for 2.5 cups of flour to make 24 cookies. How many cups of flour are needed to make 60 cookies?

A.4.5 cups

B.5.5 cups

C.6.0 cups

D.6.25 cups

Explanation: Set up a proportion: 2.5/24 = x/60. Cross-multiply: 24x = 2.5 × 60 = 150. Solve: x = 150/24 = 6.25 cups.

4Which of the following is equivalent to 0.045?

A.45/100

B.9/200

C.45/1000

D.9/2000

Explanation: 0.045 = 45/1000. Simplify by dividing numerator and denominator by 5: 45/1000 = 9/200. So 9/200 is the simplified form.

5A worker earns $12.50 per hour and works 36 hours in a week. If overtime (hours over 40) is paid at 1.5 times the regular rate, what are the worker's total earnings for a week in which they work 44 hours?

A.$550.00

B.$575.00

C.$600.00

D.$625.00

Explanation: Regular pay for 40 hours: 40 × $12.50 = $500. Overtime rate: $12.50 × 1.5 = $18.75/hour. Overtime pay for 4 extra hours: 4 × $18.75 = $75. Total: $500 + $75 = $575.

6Order the following numbers from least to greatest: −3.2, −1/4, 0.5, −7/2.

A.−7/2, −3.2, −1/4, 0.5

B.−3.2, −7/2, −1/4, 0.5

C.−7/2, −1/4, −3.2, 0.5

D.0.5, −1/4, −3.2, −7/2

Explanation: Convert to decimals: −7/2 = −3.5, −3.2 = −3.2, −1/4 = −0.25, 0.5 = 0.5. From least to greatest (most negative first): −3.5, −3.2, −0.25, 0.5, which corresponds to −7/2, −3.2, −1/4, 0.5.

7A town's population increased from 24,000 to 30,000 over five years. What was the percent increase?

A.20%

B.25%

C.30%

D.6%

Explanation: Percent increase = (new − old)/old × 100 = (30,000 − 24,000)/24,000 × 100 = 6,000/24,000 × 100 = 0.25 × 100 = 25%.

8What is the least common multiple (LCM) of 12 and 18?

A.6

B.36

C.72

D.216

Explanation: Prime factors: 12 = 2² × 3 and 18 = 2 × 3². LCM takes the highest power of each prime: 2² × 3² = 4 × 9 = 36.

9Simplify: (−4)² − 3 × (−2) + 5.

A.11

B.27

C.17

D.21

Explanation: Follow order of operations (PEMDAS). (−4)² = 16. Then 3 × (−2) = −6. So 16 − (−6) + 5 = 16 + 6 + 5 = 27.

10A car travels 240 miles on 8 gallons of gasoline. At this rate, how many miles can it travel on a full tank of 12 gallons?

A.280 miles

B.320 miles

C.360 miles

D.400 miles

Explanation: The car gets 240 ÷ 8 = 30 miles per gallon. At 30 mpg for 12 gallons: 30 × 12 = 360 miles.

HiSET Math Study Tips from Top Performers

1Focus first on Algebraic Concepts — at ~45% of the exam, mastering linear equations, inequalities, and graphing will have the biggest impact on your score.

2Use the provided formula sheet: you do not need to memorize area, volume, or Pythagorean theorem formulas, so spend your study time understanding when and how to apply them.

3Practice interpreting graphs and tables — data analysis questions are common and test your ability to read bar charts, line graphs, pie charts, and scatter plots quickly.

4Work through word problems step by step: translate words into math expressions, identify what is being asked, and check your answer against the original problem.

5Eliminate clearly wrong answers on test day. If you are unsure, rule out answers that are too large, too small, or the wrong unit, then guess from the remaining options.
