NEET Attempt Strategy Calculator

The National Eligibility cum Entrance Test (NEET UG), conducted by the National Testing Agency (NTA), is a single 180-minute paper of 180 compulsory questions — 45 each in Physics and Chemistry, and 90 in Biology — worth a maximum of 720 marks. Every correct answer earns +4, every wrong answer costs −1, and anything left blank scores 0. That penalty is what makes "how many should I attempt?" a real strategic question rather than "attempt everything".

This calculator splits your paper into the questions you answer confidently and the questions you'd guess, then works out your expected raw score and shows where your accuracy sits relative to the 20% break-even line — the point below which attempting starts costing you marks.

The break-even math on this page applies uniformly across the paper, but the 180 questions themselves aren't evenly split — Biology alone carries half the total marks:

Because Biology is worth as much as Physics and Chemistry combined, the same accuracy swing costs or gains twice as many marks there. A candidate deciding where to spend extra guessing time on exam day gets more expected value from tightening Biology accuracy than an equivalent effort in either of the other two subjects.

The +4/−1 scheme turns each block of attempts into an expected number of correct and wrong answers, then into marks:

Raw score = (4 × total correct) − (1 × total wrong)  ·  Unattempted × 0 = 0

• Confident block: correct = attempts × accuracy%, wrong = attempts − correct.
• Guess block: correct = guesses × guess-success%, wrong = guesses − correct.
• The two counts are added, then the combined attempts are capped at the 180-question paper.

A neat closed form falls out of this: for A attempted questions at accuracy p, the expected raw score is A × (5p − 1). That single expression is why the break-even lands at exactly 20% — set 5p − 1 = 0 and p = 0.2. If you just want to convert a score to a percentage of the maximum, the general percentage calculator handles any out-of-total conversion.

Take a candidate who answers 160 questions confidently at 85% accuracy and skips the remaining 20. The table below is generated live by the same engine the calculator uses.

Their expected raw score is 520 out of 720 — 136 correct earning 544 marks, minus 24 wrong costing 24 marks. The 20 blanks neither helped nor hurt. Pushing accuracy up, or converting a few skips into above-break-even guesses, is what moves this number.

Because a wrong answer costs a mark, attempting a question is only worth it when your chance of getting it right clears the break-even. The table below fixes a full 180-question attempt and varies only the accuracy, so you can see the raw score cross zero exactly at 20%:

Notice how steep the swing is near the bottom: moving from 10% to 20% accuracy adds 180 marks, while the same 10-point jump from 80% to 90% adds a smaller amount relative to where you already are. Accuracy near the break-even line is where careless attempts do the most damage. For a completely separate but related exam tool, the CUET score & percentile calculator applies the same negative-marking logic to the +5/−1 CUET scheme, and the attendance calculator helps you plan the study runway that builds this accuracy in the first place.

• Uses the NEET UG 2025-onward pattern: 180 compulsory questions, no optional Section B, single 180-minute shift, +4/−1/0 marking. The marking scheme and question count are set by NTA each cycle and are time-sensitive — re-check them against the current NTA information bulletin.
• The expected score is a statistical estimate. It treats your accuracy and guess-success as applying uniformly across the relevant questions; your real exam-day result depends on which specific questions you get right or wrong.
• Guessed questions are modeled as attempts additional to your confident set, with the combined total capped at 180. If your two inputs add up to more than 180, the total is capped and unattempted floors at 0 — the tool does not otherwise check that the two figures describe one consistent paper.
• This tool models raw marks only. It does not convert your score into All India Rank, percentile or college cut-offs — none of those has a fixed formula, and all vary every year with paper difficulty and the candidate pool. NTA's rule of awarding +4 for a dropped or multiple-correct question is also not modeled.
• "Attempt strategy" here means how many questions to answer or guess during the exam — not how many times you sit NEET. Eligibility rules such as attempt caps or age limits are a separate matter and out of scope.
