Should you guess?
Expected marks for one guess, picking at random among the options you could not rule out. A positive number means guessing pays on average.

About the Exam Score Calculator with Negative Marking
Count your right and wrong answers — from an answer key, a response sheet or a mock test — and the calculator works out your score with the exam’s own marking scheme: marks for each right answer minus the penalty for each wrong one, section by section, with the questions you left out, your accuracy and the marks negative marking cost you.
Presets follow the official bulletins: JEE (Main) 2026 papers 1, 2A and 2B, NEET (UG) 2026, CUET (UG) 2026, UPSC Civil Services Prelims 2026 (with the qualifying CSAT), SSC CGL 2026 Tier-I and Tier-II, GATE 2027 and CAT 2026. For any other exam, set your own marks and penalties — fractions such as 1/3 work. A last panel shows whether guessing pays: the expected marks of a guess when 4, 3 or 2 options are left.
How to use it
- Choose the exam. Open “About this marking scheme” to see how it is marked.
- For each section, type how many questions you got right and how many wrong. Questions left blank are worked out from the total.
- For another exam, choose Your own marking scheme (or press Change the marking scheme to start from a preset) and type each section’s questions, marks and penalty.
- Read your score, the section table and the guessing advice, then Copy result or Download CSV.
Examples
Mathematics 18 right, 4 wrong; Physics 20, 3; Chemistry 22, 2
231 / 300: (18 + 20 + 22) × 4 − (4 + 3 + 2) × 1 = 240 − 9
Physics 35/6, Chemistry 38/4, Biology 80/7 (right/wrong)
595 / 720: 153 × 4 − 17 × 1, with 10 questions left out
60 right, 13 wrong
111.33 / 200: 60 × 2 − 13 × ⅔
Paper II (CSAT) only has to reach 33% (66 of 200).
1-mark MCQs 12/4, 1-mark MSQ/NAT 8/3, 2-mark MCQs 10/5, 2-mark MSQ/NAT 9/4
53.33 / 100: wrong MCQs cost ⅓ or ⅔; MSQ and NAT answers cost nothing
MCQs 34 right, 12 wrong; non-MCQs 9 right, 4 wrong
117: (34 + 9) × 3 − 12 × 1 — wrong non-MCQ answers cost nothing
The marking schemes
- JEE (Main) 2026, Paper 1: 75 questions, 300 marks — in each of Mathematics, Physics and Chemistry, 20 MCQs and 5 numerical-value questions, all +4 / −1, 0 if unanswered. Papers 2A and 2B: 400 marks with the same +4 / −1 (the B.Arch Drawing Test is marked out of 100).
- NEET (UG) 2026: 180 compulsory questions (Physics 45, Chemistry 45, Biology 90), 720 marks, +4 / −1.
- CUET (UG) 2026: 50 compulsory questions per test paper, +5 / −1; up to five papers.
- UPSC Civil Services Prelims 2026: two papers of 200 marks with four alternatives per question; a wrong answer, or more than one answer, costs one-third of the question’s marks — 2/3 in Paper I (100 questions of 2 marks), 5/6 in Paper II (80 questions of 2.5 marks). Paper II is qualifying at 33%.
- SSC CGL 2026: Tier-I has 100 questions of 2 marks with 0.50 off for a wrong answer; Tier-II Paper-I has 3 marks a question and 1 off for a wrong answer, with the Computer Knowledge section qualifying only.
- GATE 2027: 65 questions, 100 marks; wrong MCQs cost 1/3 (1-mark) or 2/3 (2-mark); MSQs and numerical answers have no negative marks.
- CAT 2026: MCQs +3 / −1; non-MCQ (type-in) answers +3 with no penalty.
Is it worth guessing?
With a right answer worth c, a wrong one costing w and k options left to choose from, a random guess is worth on average c ÷ k − w × (k − 1) ÷ k. Guessing pays whenever your chance of being right is above w ÷ (c + w).
- JEE and NEET (+4 / −1): even a blind guess among 4 options gains 0.25 marks on average; answer when you are more than 20% sure.
- UPSC (one-third penalty) and CAT MCQs (+3 / −1): a blind guess among 4 options is exactly break-even; ruling out one option makes it pay.
- No-penalty questions (GATE MSQs and NATs, CAT non-MCQs): never leave them blank.
These are averages over many questions, not a promise for one — and some exams use the proportion of wrong answers to break ties (JEE Main does), so careless guessing has a cost beyond the marks.
Raw marks, NTA scores and normalisation
The calculator gives your raw marks. For papers held in several shifts, NTA converts raw marks into NTA scores (JEE Main, CUET), and SSC normalises CGL marks before setting merit and cut-offs, so your rank is decided on those figures, not on raw marks alone.

Limitations
- Marking schemes can change from one year to the next: check the current bulletin or notice of your exam before relying on a preset.
- Dropped or bonus questions, multiple correct options and answer-key changes are not applied — adjust your right and wrong counts for them.
- The score is raw marks; ranks, percentiles and cut-offs depend on normalisation and on everyone else’s marks.

Frequently asked questions
How is the JEE Main score calculated?
+4 for each correct answer and −1 for each wrong one, in the MCQs and in the numerical-value questions alike; unanswered questions get 0. With 60 right and 9 wrong: 240 − 9 = 231 out of 300.
How much is deducted for a wrong answer in UPSC Prelims?
One-third of the marks of that question: 2/3 of a mark in Paper I (2-mark questions) and 5/6 in Paper II (2.5-mark questions). Marking more than one answer counts as wrong; a blank costs nothing.
Is there negative marking in NEET?
Yes: +4 for a correct answer and −1 for each incorrect option marked, out of 720 marks for 180 questions.
Do numerical answer questions have negative marking?
In JEE (Main) 2026, yes: −1 for a wrong numerical value. In GATE, no: NAT and MSQ questions carry no negative marks. In CAT, non-MCQ answers have no negative marks either.
Should I attempt a question I am not sure about?
Answer when your chance of being right is above w ÷ (c + w): 20% for +4 / −1, 25% for UPSC and CAT MCQs. If you can rule out even one of four options, a guess pays on average in all of these exams.
Can I use it for my college or state exam?
Yes. Choose Your own marking scheme and type, for each section, the number of questions, the marks for a right answer and the marks taken off for a wrong one.
