How CAT Quant Scoring Works: Marks and Time Limits

QUANT

Most aspirants know the marking scheme roughly and have never worked through what it implies. That gap matters more than it sounds, because almost every strategy decision in the quant section is downstream of three rules that take two minutes to learn and change how you should behave for the whole forty.

This piece sets out what is actually fixed, what varies between papers, and what the marking arithmetic means for attempts, guessing and time. Where a figure is from a specific paper rather than a permanent rule, it is labelled as such, because treating one paper's structure as CAT's fixed shape is the commonest error in this territory.

The Three Rules That Are Fixed

Start with what does not move between papers, because everything strategic follows from it.

The first is the marking scheme. Three marks for a correct answer, one mark deducted for an incorrect multiple choice answer, and zero for a question left unattempted. That asymmetry between minus one and zero is the single most consequential fact in CAT strategy.

The second is that type-in-the-answer questions, where you enter the answer rather than choosing from options, carry no negative marking. A wrong TITA answer costs nothing.

The third is the sectional time limit. Each section runs to a hard limit of forty minutes and you cannot move between sections or return to one after its time expires. Time saved in quant does not fund anything elsewhere.

What the Marking Scheme Implies

The rules are simple and their consequences are not intuitive, which is why so much attempt advice is wrong.

The Arithmetic Worth Running Once

Take a paper of 66 questions worth 198 marks. Suppose a candidate attempts 63 of them at 41 percent accuracy, so roughly 26 correct. Those 26 are worth 78 marks gross, and the net comes out at 54. The 37 wrong attempts cost 24 marks against simply leaving them blank.

That is not an argument for a specific attempt count, since the right number depends on you and on the paper. It is the demonstration that an attempt with poor odds has a negative expected value while a blank has a value of exactly zero.

Why Attempt Targets Keep Being Published Anyway

Because a number is easy to remember and impossible to falsify. A candidate who follows one and scores well credits it; one who follows it and scores badly assumes they executed poorly. Nothing about the outcome ever tests the target.

The Sectional Limit Changes Pacing

Because time cannot be borrowed, a single overrunning question is expensive in a specific way: it costs you the two questions you would otherwise have taken in this section. That is the argument for a walk-away time decided before the section starts.

Outcome	MCQ	Type in the answer
Correct	Plus three marks	Plus three marks
Incorrect	Minus one mark	Zero
Unattempted	Zero	Zero
Strategy implication	Attempt on good odds only	Attempt whenever reasoned

What Varies Between Papers

Three things move, and treating any of them as fixed produces plans that do not survive the day.

The question count is the first. In the 2022 paper quant carried 22 questions worth 66 marks, alongside VARC at 24 and DILR at 20. Recent papers have run roughly 66 to 68 questions in total and therefore 198 to 204 marks. There is no permanent structure to memorise.

The MCQ and TITA split is the second, and it is the most underrated. A paper with more type-in questions is materially more forgiving to attempt, even if the questions are no easier, because more of the section carries no penalty.

The internal mix of areas is the third. It has moved, which is why frequency is a guide to where to start rather than a forecast.

The Weightage Question, Answered Honestly

Aspirants ask about chapter weightage expecting a published table, and none exists.

CAT publishes a general syllabus that defines what can be asked. It does not prescribe a fixed chapter-wise or area-wise breakdown with marks attached, so any article giving exact percentages per area is presenting a count from past papers as though it were an official allocation.

What can be said is a recurrence ordering that has held up. Arithmetic and algebra have recurred most heavily, with geometry and number system next and modern mathematics contributing a smaller share. Within arithmetic, percentages, ratio and proportion, averages, profit and loss, time speed and distance, and time and work recur most.

Use that to decide where to begin rather than what to include. A lower share is not a zero share, and approachable questions from the lighter areas appear regularly. Sequencing by return is a scheduling decision; deleting an area is a coverage decision, and only the first is defensible.

What This Means for the Forty Minutes

Four behaviours follow directly from the scoring rules, and none of them is about solving faster.

Scan before committing, because you cannot judge whether a question is worth attempting without knowing what the alternatives are. That costs a few minutes and it converts an arbitrary start into a deliberate one.

Attempt on recognition rather than on a quota. If you can see the first two steps within about twenty seconds, the odds are usually good. If you cannot, they usually are not, and a blank costs nothing.

Hold a walk-away time. Because time is section bound, an overrun is paid for by other quant questions, and a partly built solution at minute four feels close for reasons unrelated to whether it will resolve.

Take every reasoned type-in. This is the one place where the correct behaviour is unambiguous and where aspirants most consistently leave marks untouched.

What to Measure Afterwards

Accuracy on committed questions, marks lost to wrong MCQs, and type-in questions left blank. Those three numbers tell you whether the scoring rules have actually changed your behaviour, which a sectional total cannot.

The Recurrence Side of the Plan

Depth in the heavily recurring areas is what makes the twenty second recognition judgment reliable, which is why work in chapters like time, speed and distance practice pays twice: once in technique and once in faster decisions. Our guide on the quant topics you cannot skip covers the coverage floor beneath any priority order.

Where Percentile Enters, and Where It Does Not

One further distinction belongs here, because it is where scoring questions usually end up and where most bad advice lives.

Everything above concerns your raw score, which comes entirely from your own paper and is computable from the marking rules. Your percentile is a different object: it is your position relative to everyone who sat the exam, so it depends on how the whole cohort performed. There is no fixed mapping between the two.

Normalisation adds a further layer. CAT runs across multiple slots and those slots do not receive identical papers, so a process exists to make scores comparable across them. That is another reason a raw figure cannot carry a fixed percentile label, and it is also the answer to the worry that a harder slot will sink you.

The practical consequence is that any claim of the form "X marks equals Y percentile" is converting a variable relationship into a constant. Past year tables are accurate records of what happened once; used as forecasts they mislead in both directions, producing false confidence in some candidates and unnecessary despair in others.

The Summary Worth Carrying In

Three marks for correct, minus one for a wrong MCQ, zero for a blank, no penalty on type-in questions, forty minutes that cannot be borrowed from or lent to any other section.

Everything else people argue about, attempt counts, question order, how many to leave, is an application of those five facts to a paper whose exact shape you will not know until the clock starts. The count of questions has moved between years, the MCQ and TITA split has moved, and the internal mix has moved. The rules have not.

Which is why the useful preparation is not memorising a structure. It is building the recognition that lets you judge odds quickly and the discipline to act on the difference between minus one and zero, both of which work on any paper.

If you know the marking scheme and your attempt behaviour does not reflect it, that gap is worth closing before anything else. A CAT preparation strategy review will show the size of it, and a personalised CAT preparation plan keeps the timed work in your week.
