Short answer: Net Score = Correct Answers − (Wrong Answers ÷ 4). This is the formula used in standardized multiple-choice exams to discourage random guessing — every 4 wrong answers deduct 1 correct answer from your score. Below is a step-by-step breakdown along with answers to common questions.
What Is the Net Score Formula?
Since these exams are multiple-choice with several options per question, there's a real chance of guessing correctly at random. That's why each wrong answer doesn't reduce your score by a full point, but by 1/4 of a point. Blank answers are never counted — neither as a plus nor a minus.
Step-by-Step Example
Let's say a math test has 40 questions, and you answered them as follows:
❌ Wrong: 8
⬜ Blank: 0
Net = 32 − (8 ÷ 4) = 32 − 2 = 30 net
The formula doesn't change when there are blank answers — only correct and wrong counts are used:
Net = 25 − (20 ÷ 4) = 25 − 5 = 20 net
How Does Net Score Turn into a Final Score?
Once you calculate your net score for each subject, those numbers are combined with statistical coefficients published after the exam to produce your final score. This last conversion step is done centrally, so it can't be replicated exactly on your own — but your net score is still the most practical way to track your own progress throughout your prep.
Frequently Asked Questions
No. Only correct and incorrect answers are counted in the net score calculation; blank answers are not counted at all.
No. A wrong answer doesn't cancel a correct answer entirely — it reduces your correct count by 1/4. In other words, 4 wrong answers cancel out 1 correct answer.
The exam authority converts net scores into final scores using statistical coefficients published after the exam. Your net score remains the most reliable way to track your own performance.
