Quant in the Last 30 Days: What to Revise and What to Drop

Quant

With about a month left, the Quant question changes. You are no longer asking what to learn. You are asking what to do with the hours that remain, and the honest answer is that most of the gains now come from what you stop doing, not from what you add.

CAT 2026 is on Sunday 29 November, so today, 28 October, you have roughly four and a half weeks. This guide gives you a way to sort your Quant work into three buckets: revise, hold and park. It also names the activities to drop, which are habits and not chapters.

What Changes in the Last Month of Quant

For most of your preparation, adding is the right move. You learn a chapter, practise it, and move to the next. In the last month, that logic reverses. A new chapter learnt at this stage rarely gets enough repetition to become reliable under exam pressure, while a chapter you already know can still gain a lot from sharpening.

The exam also tests Quant under a clock. CAT has three sections of forty minutes each, so your Quant skill is the combination of knowing the method and executing it fast. In the last month, the second part has more room to improve than the first. Speed and accuracy on topics you already know are the cheapest gains available.

That is why the plan below starts from your own data. You are not working from a textbook list. You are working from the questions you have actually solved, the ones you got wrong, and the ones that took too long.

Revise, Hold, Park: A Three Bucket Sort

Take every Quant chapter and place it in one of three buckets. The sort should take under an hour and you should do it with your last few mocks and your practice log open.

Revise is the bucket that deserves most of your time. These are chapters where your accuracy is middling, the mistakes are repeatable, and the topic is one CAT has historically asked often. Hold is for chapters you are confident in. Park is the bucket people misread, so it needs a clear definition.

Parking is not skipping. A parked chapter gets one timed set in the month, so you still recognise the question types and can attempt an easy one if it appears. It does not get new theory, long worked-example sessions or a place in your daily plan. The distinction matters because CAT does not publish a fixed chapter list, and any chapter can show up.

What Goes in the Revise Bucket

Chapter priority should follow historical frequency, which is a pattern from past papers and not a prediction. Historically, arithmetic and algebra together make up the largest share of CAT Quant. Within arithmetic, percentages, ratio, averages, profit and loss, time, speed and distance, and time and work recur most and underpin other questions.

So the first candidates for the revise bucket are the arithmetic and algebra chapters where your mock data shows avoidable errors. Look for chapters where you lose marks to a small set of repeat mistakes, such as a unit slip in time and work or a sign error in a quadratic. Those are the chapters where an hour of focused review pays off quickly.

Geometry and number system come next in the historical order. They are meaningful contributors, but behind arithmetic and algebra, and they tend to reward pattern recognition. If your errors there come from forgetting a standard result, a short targeted review of that result is enough. Our guide on the 20 Quant topics you cannot skip before CAT 2026 lists the areas worth checking.

Bucket	What belongs here	What to do with it
Revise	Close to mastery, repeat errors, historically frequent	Daily timed sets, error log review
Hold	Solid accuracy and speed	Short timed set twice a week
Park	Rare or costly, low accuracy so far	One timed touch this month

A Worked Sort from Three Mocks

Here is an illustrative example, with made-up numbers, of how the sort works. Suppose that across three mocks you tagged your wrong or abandoned Quant questions and found these counts: percentages 4, time and work 6, quadratics 5, geometry 7, number system 2, permutation and combination 3, and logarithms 1.

Time and work and quadratics are historically frequent and show repeat errors, so they go to revise. Geometry has the highest count, but a closer look shows the mistakes come from five different results you have not memorised. That is also a revise case, with a fix as simple as a one-page list. Percentages is close, and goes to hold after one more timed set.

Number system and logarithms have low counts, so they stay in hold. Permutation and combination has a middling count, but the errors are scattered across hard variants, so you park it with a single timed set this month. The point is not these exact numbers. It is that every chapter gets a decision, and every decision has a reason you can state.

What to Drop: Habits, Not Chapters

The title of this guide says drop, and it is worth being precise. You are not dropping chapters. You are dropping four activities that feel like preparation but rarely move your score in the last month.

The first is the new theory binge, learning a chapter from scratch with long video lectures. The second is hard-question hunting, searching for the most difficult problems in a chapter because they feel more serious. CAT questions are not usually of that type, and difficult problems at this stage mostly dent your confidence.

The third is note rewriting. Neatly recopying formulas gives a feeling of order but little retrieval practice. A short list you actually test yourself on is better. The fourth is untimed practice. Solving without a clock builds a skill you will not have in the exam, and the exam is timed.

In place of those, spend the hours on timed sets from the revise bucket, a review of every wrong answer, and a few full mocks. If you want to check your balance, a free CAT strategy review can show where your hours are going against where your marks are.

A Weekly Rhythm for the Last Month

A simple rhythm keeps the three buckets in proportion. Most of your Quant time goes to revise, with the rest split between hold and a single weekly park touch. You can adjust the shares to your own profile, but the structure should stay.

In the first week, do the sort and start timed sets on the top revise chapters. Keep an error log with three columns: the chapter, the cause of the mistake and the fix. In the second and third weeks, add full mocks and review them against the log, moving chapters between buckets as the data changes. A chapter that improves moves from revise to hold.

In the last week, you taper. Reduce volume, keep timed sets short, and review your error log and formula list. The final days are about holding what you have. Our piece on revising formulas the night before CAT, or resting covers the very last stretch.

Mental maths can also be worth a short daily slot. Squares, cubes and common fractions saved in memory speed up almost every chapter, and our guide to four recall tables to memorise for CAT Quant gives you a compact set.

Common Traps When You Sort Your Chapters

The sort can go wrong in a few predictable ways. The first is parking a chapter because you dislike it. Dislike is not data. If your accuracy there is low but the chapter is historically frequent, it belongs in revise, with extra attention on the specific errors, and not in park.

The second is keeping a chapter in hold forever. A chapter that feels solid can slip if it gets no attention. Short timed sets twice a week are enough to keep it alive, and a quick check on those sets will tell you early if accuracy is falling.

The third is treating the buckets as permanent. They are a snapshot of this week. After every mock, update them. Aspirants who sort once and never revisit end up following a plan that no longer matches their data.

Finally, avoid sorting by how a chapter feels in the middle of a hard session. Use numbers. Accuracy, time per question and the error log give a clearer picture than mood. If you want your schedule to follow the sort automatically, a CAT study planner can lay out the weeks for you.
