CAT accuracy vs attempts chart: expected value of an MCQ by confidence level, with the bet-on-it rule for deciding whether to attempt.

Ask an aspirant how to improve their score and most will say the same thing: attempt more questions. It feels obviously true. More attempts, more marks. But CAT has negative marking, and that one rule turns the intuition into a trap. Past a certain point, attempting more questions lowers your score rather than raising it. Understanding CAT accuracy vs attempts as a single tradeoff, not two separate goals, is what separates aspirants who plateau from those who climb.

This guide puts numbers on the tradeoff. You will see the expected-value math of a single MCQ, the confidence threshold that should decide whether you attempt, and the section-wise accuracy benchmarks that match different percentile targets. None of it is complicated; it just runs against instinct.

Run your own attempt and accuracy numbers against a target percentile.

Why "more attempts" is often the wrong move

Picture two aspirants with identical ability. The first attempts 45 questions at 80 percent accuracy. The second, chasing volume, attempts 55 but their accuracy on those extra ten low-confidence questions is only 30 percent. The second aspirant attempted more and scored less, because the extra attempts brought in wrong answers, and each wrong MCQ does not just earn zero, it subtracts a mark. Attempts and accuracy are not independent dials you turn up separately. They move together, and pushing one too hard drags the other down.

This is why "attempt more" is good advice only at the bottom of the curve, where an aspirant is leaving easy marks untouched. Once you are already attempting the questions you can reasonably solve, the next attempt comes from a shakier pool, and that is exactly where negative marking starts working against you. Knowing which side of that line you sit on is the heart of a smart CAT attempt strategy.

The CAT accuracy vs attempts math

CAT scores a correct MCQ at plus three and a wrong one at minus one. Type-in-the-answer questions carry no penalty. For an MCQ, if your chance of being right is p, the expected value of attempting is three times p, minus one times the chance of being wrong. Written out, that is four times p, minus one. A blank scores zero. So attempting beats skipping whenever four p minus one is above zero, which happens once p passes 25 percent.

SituationChance correctExpected valueReading
Random guess, 4 options25%0Break-even with a blank
Eliminate 1 option~33%+0.33Slightly positive
Eliminate 2 options50%+1.0Clearly worth it
Confident solve~85%+2.4The marks you build on
TITA, any reasonable shotvariesnever negativeNo penalty, so attempt

The table says something surprising: in pure marks, a random four-option guess breaks even, and eliminating even one option makes an attempt positive. So why do low-confidence attempts wreck scores in practice? Because the marks math is only half the story, and the other half is where most aspirants lose. The elimination logic behind the middle rows is worth practising on its own, which we cover in the CAT educated guess strategy.

The real confidence threshold to attempt

The pure math says attempt anything above a random guess. Real exam conditions push that threshold much higher, for two reasons the math leaves out.

First, time. A question you are 35 percent sure of is rarely a quick one; it usually takes two or three minutes of struggle. Those minutes could have banked a near-certain mark elsewhere, so the true cost of a shaky attempt is not just its small negative risk but the sure mark you did not collect instead. Second, calibration. Aspirants consistently overrate their confidence. A question that feels like a 60 percent chance is often closer to 40 once you check against results. Stack those two effects together and the safe attempt threshold climbs from the textbook 25 percent to something nearer two-thirds confidence in practice.

Pro Tip: the bet-on-it test

Before attempting a borderline MCQ, ask whether you would put real money on your answer. If you would happily bet, attempt it. If you would hesitate or want to change your pick, treat it as a skip and move on. The bet test cuts through inflated confidence because money makes you honest in a way a vague feeling of "probably right" does not. It is the fastest calibration check you can run mid-exam.

Section-wise accuracy benchmarks

How accurate you need to be depends on your target and varies a little by section. The benchmarks below are accuracy on attempted questions, not on the whole paper, since unattempted ones neither help nor hurt. Use them as a check: if your accuracy sits below the row for your target, the fix is to attempt fewer, surer questions, not more.

TargetVARC accuracyDILR accuracyQA accuracy
90 percentile~72%~75%~70%
95 percentile~80%~82%~78%
99 percentile~87%~88%~85%

DILR accuracy tends to run highest at every target, and the reason is selection. Strong scorers attempt only the sets they have understood, so once they commit, they are usually right. That is the tradeoff working as intended: fewer, better-chosen attempts produce higher accuracy and a higher net score than a wider, shakier net. The gap between your mock accuracy and these benchmarks is also one of the clearest signals of how your real CAT might differ from your practice scores, which we unpack in why your mock score is not your CAT score.

The accuracy-attempts mistakes that quietly cost marks

Three habits keep aspirants stuck on the wrong side of the tradeoff:

  • Treating attempts as the score. Counting attempts in a mock and feeling good about a high number ignores the wrong answers dragging the net down. Track net marks, not attempts.
  • Trusting felt confidence. The feeling of "probably right" is systematically inflated. Without a calibration check like the bet test, you will attempt more coin-flips than you think.
  • Ignoring time cost. A low-confidence question that takes three minutes does double damage: small negative risk plus a sure mark not collected elsewhere.

Common questions on accuracy vs attempts

Is accuracy or number of attempts more important in CAT?
Neither alone, because they are one tradeoff rather than two goals. Your score is the net result of attempts multiplied by accuracy, minus the negative marking from wrong MCQs. More attempts help only while your accuracy on those extra questions stays high enough to beat the penalty. Below a certain confidence, each extra attempt lowers your net score instead of raising it. So the real target is not maximum attempts or maximum accuracy, but the combination that produces the highest net marks for your level.
How accurate should I be in CAT?
It depends on your target. As a rough guide, a 90 percentile aim can work at around 70 to 75 percent accuracy on attempted questions, while a 99 percentile aim usually needs about 85 to 90 percent. Higher targets demand higher accuracy because the score-to-percentile curve is steep near the top, so wrong answers cost more there. The accuracy figure that matters is accuracy on what you attempt, not on the whole paper, since unattempted questions neither help nor hurt.
What is the confidence level needed to attempt a CAT MCQ?
On pure marks, attempting beats skipping whenever you are better than a random guess, since a four-option MCQ has a break-even at 25 percent. But that ignores two real costs: the time a shaky question steals from surer marks, and the fact that aspirants tend to overestimate their confidence. Once you fold those in, the practical rule is to attempt only when you are clearly past roughly two-thirds confidence. A simple test is whether you would bet money on your answer; if you would hesitate, treat it as a skip.
Does attempting a question at 50 percent confidence hurt my CAT score?
In pure marks a genuine 50 percent chance is still positive, but the catch is that felt confidence is usually inflated, so a question that feels like 50 percent is often closer to 30. Add the time it eats, and a string of fifty-fifty attempts quietly drags your net score down even though each one felt reasonable. The safe habit is to trust attempts you are clearly sure of and let the true coin-flips go, especially when surer marks are still available elsewhere.

Find your accuracy sweet spot from real mock data

A free strategy session with an Optima Learn mentor reads your attempt and accuracy split by section and confidence level, then sets the attempt count that produces your best net score instead of your highest attempt count.

Get My Accuracy Plan

Stop chasing attempts as if they were the score. They are one half of a tradeoff that negative marking governs, and past your real confidence line, each extra attempt costs more than it pays. Learn the expected-value math, run the bet test on borderline questions, and hold your accuracy at the benchmark for your target. Do that and you will often attempt slightly fewer questions and score noticeably more, which is the whole point. Drill the habit on the Optima Learn question bank until skipping a coin-flip feels as natural as solving a sure thing.
