Calculator Use in SAT Subject Test Math 2 Formula and Mathematical Explanation
The scoring for the SAT Subject Test Math 2 is straightforward, but understanding its components is crucial for strategic calculator use in SAT Subject Test Math 2. The raw score is calculated based on correct, incorrect, and omitted answers. This raw score is then converted to a scaled score between 200 and 800.
Step-by-Step Raw Score Derivation:
The College Board uses a specific formula to calculate your raw score:
Raw Score = (Number of Correct Answers) - (Number of Incorrect Answers × 0.25)
Questions left blank (omitted) do not affect your raw score; they neither add points nor subtract points. The 0.25 point deduction for incorrect answers is often referred to as a “quarter-point penalty” or “guessing penalty.” This penalty is designed to discourage random guessing.
For example, if you answer 40 questions correctly, 8 questions incorrectly, and omit 2 questions:
- Correct Answers: 40 points
- Incorrect Answers Penalty: 8 × 0.25 = 2 points
- Raw Score = 40 – 2 = 38
This raw score of 38 would then be converted to a scaled score using a specific conversion table for that test administration. Our calculator provides an estimated scaled score range based on typical conversions.
