CAT Preparation in 6 Months: A Month-by-Month Plan
Six months is enough time for CAT, and it is enough with room to spare — provided two things start on day one and never stop: daily reading and arithmetic. Everything else can be sequenced around them.
The plan below is built around a specific constraint most six-month plans ignore: VARC takes three to four months to move, while quant moves in weeks. Sequence the two identically and you will finish with a lopsided profile that sectional screens punish.
Reading and arithmetic. Both, from week one.
Reading because it is the slowest thing to improve. Arithmetic because everything else in quant compounds on top of it. Delay either and the last two months become a rescue operation rather than a peak.
Quick Answer (30-Second Read)
Realistic daily load
2–3 focused hours
More on weekends
Mock count
25–30 full mocks
Plus 50–60 sectionals
- Months 1–2: arithmetic, daily reading, basic algebra. One mock a month, score ignored.
- Months 3–4: geometry, number system, DILR process. One mock a week, each analysed properly.
- Months 5–6: modern maths, two mocks a week, error log drives every study block.
- Reading never leaves the schedule — it appears in month one and runs through to the exam.
- When the schedule slips, drop topics not habits. Skipping a week of reading costs more than skipping a week of geometry.

CAT Mock Test — VARC, DILR & QA on the real interface
Take one in month one, before you feel ready. The score does not matter — seeing a section close at 40 minutes changes how you plan the other five months.
Month by month
| Month | Quant | VARC | DILR | Testing |
|---|---|---|---|---|
| 1 | Arithmetic furniture, then percentages and ratio | Daily article + one-line summary | — | 1 mock. Ignore the score entirely |
| 2 | Profit-loss, interest, time-work, time-speed-distance | Daily reading + para jumbles, odd-one-out | Start: 3 sets a week, untimed | 1 mock, 45-minute review |
| 3 | Algebra — equations, inequalities, functions | Reading + 3 RC passages a week, untimed | 4 sets a week, selection rubric introduced | 2 mocks + weekly sectionals |
| 4 | Geometry, mensuration, number system | RC under timing — 3 passages in a sitting | Sets under timing, 4-minute abandon rule | 4 mocks, one per week |
| 5 | Modern maths + revision of weak arithmetic | Full 40-minute VARC sections | Full 40-minute DILR sections | 6–8 mocks, two per week |
| 6 | Error-log topics only. No new material | Reading continues; RC from past papers | Selection drill twice weekly | 8 mocks, tapering in the final week |
Two things are deliberately absent from month one: DILR and modern maths. DILR because practising set selection before you can solve sets teaches the wrong lesson, and modern maths because it is the smallest block and the slowest to make fast — it earns its place only once the larger areas are solid.
A week in practice
Roughly 15 hours, which is what two to three focused hours a day comes to.
| Day | Main block | Non-negotiable | Time |
|---|---|---|---|
| Mon | Quant topic — current month's focus | Daily article | 2h |
| Tue | DILR sets | Daily article | 2h |
| Wed | Quant topic + practice set | Daily article | 2h |
| Thu | VARC — RC passages or verbal ability | Daily article | 2h |
| Fri | Sectional test in your weakest section | Daily article | 1.5h |
| Sat | Full mock + 45-minute review | Daily article | 3h |
| Sun | Error-log topics from the mock. Nothing else | Daily article | 2.5h |
Saturday and Sunday are one unit
The mock on Saturday produces the diagnosis that dictates Sunday. Do not plan Sunday in advance — its content is whatever Saturday's error log names. Candidates who schedule Sunday ahead of time end up studying what they planned rather than what they need.
The Saturday mock is what makes this plan work
Without a fixed weekly benchmark, six months becomes six months of studying with no idea whether any of it is landing.
- Percentile estimate
- Sectional breakdown
- Topic-wise accuracy
Why this order and not another
Most six-month plans allocate equal attention to all three sections from the start. That looks balanced and produces an unbalanced result, because the three sections improve at completely different rates.
| Section | Time to visible improvement | What that implies |
|---|---|---|
| Quant | 4–6 weeks per topic | Can be sequenced. Late topics still have time to land |
| DILR | 6–10 weeks for selection process | Start by month two. Process before speed |
| VARC | 3–4 months | Must start day one. Nothing else compensates |
Read the VARC row again. A candidate who begins reading in month three will see the benefit arriving somewhere around the exam itself. That is the single most common way a six-month preparation produces a 99 in quant and a 70 in VARC — a profile most sectional screens reject regardless of the overall percentile.
Arithmetic sits first for a different reason: it compounds. Percentages underpin profit and loss, interest, mixtures and most data interpretation. Fluency there quietly makes four other topics faster, which is why an hour spent on it in month one is worth more than an hour spent on it in month four.
When the schedule slips — and it will
Nobody completes a six-month plan as written. The useful question is what to sacrifice, and the answer is consistent: drop topics, protect habits.
| What slipped | Cost | Recovery |
|---|---|---|
| A week of daily reading | High — the habit is the whole mechanism | Restart immediately. Do not try to catch up with three articles a day |
| A week of quant topics | Low — topics can be resequenced | Shift the schedule right by a week. No other change |
| The weekly mock | High — you lose the benchmark and the anchor | Take it late rather than skipping. Even Sunday evening beats missing |
| Mock review | Very high — the mock becomes worthless | Never skip review. Skip the next mock instead |
| Modern maths entirely | Low — smallest block | Acceptable trade if arithmetic and algebra are solid |
The fourth row is the one candidates get wrong most often. Faced with a compressed week, the instinct is to take the mock and skip the review. That produces a percentile and no learning — the exact opposite of what the hour was for. Skipping the mock entirely is strictly better than taking one you will not analyse.
If you are working full time
The plan compresses to about ten hours a week without losing its shape, provided the two day-one habits survive.
| When | What | Time |
|---|---|---|
| Weekday mornings | Daily article, before work | 25 min |
| Weekday evenings | One quant topic or DILR sets | 60–75 min |
| Saturday | Full mock + 45-minute review | 3h |
| Sunday | Error-log topics from Saturday | 2h |
Reading moves to the morning deliberately. Evening reading after a full workday tends to become scrolling, and the article is the one item that must not be negotiable. Twenty-five minutes before work is more reliable than an hour that keeps getting postponed.
On this schedule the six months hold, but the margin is thinner — so protect the Saturday mock above everything else. It is both the benchmark and the deadline that makes the weekday work happen.
Key Takeaways
- Reading and arithmetic start on day one and never stop. Everything else sequences around them.
- VARC takes 3–4 months to move, quant 4–6 weeks per topic. Equal early attention produces a lopsided profile.
- DILR starts in month two, modern maths in month five. Both are wrong to front-load.
- Saturday mock, Sunday error log. Do not plan Sunday in advance — the mock decides it.
- When the week slips, drop topics not habits. A missed week of reading costs more than a missed week of geometry.
- Never take a mock you will not review. Skipping the mock is strictly better.

Is 6 months enough for CAT preparation?
Yes, with room to spare, provided two things start immediately and continue throughout — daily reading and arithmetic. Six months fails when candidates sequence all three sections identically, because VARC takes three to four months to show improvement while quant moves in four to six weeks per topic. Start reading in month three and the benefit arrives around the exam itself, which is how a six-month preparation ends up producing 99 in quant and 70 in VARC.
How many hours a day for a 6-month CAT plan?
Two to three focused hours on weekdays with longer weekend blocks, which comes to about fifteen hours a week. Consistency matters far more than the daily total — two focused hours every day beats erratic six-hour sessions twice a week. Working candidates can compress this to around ten hours weekly without losing the plan's shape, provided the daily article and the Saturday mock both survive the compression.
What should I study in the first month of CAT preparation?
Arithmetic and daily reading, and very little else. Start with the arithmetic furniture — tables to 20, squares to 30, percentage-fraction conversions — then percentages and ratio, which underpin most of the rest of quant. Read one difficult non-fiction article every day and state its main claim in a sentence afterwards. Take one mock in month one purely to see the interface and the sectional lock, and ignore the score completely.
When should I start DILR in a 6-month plan?
Month two, and start with process rather than speed. Practising set selection before you can reliably solve sets teaches the wrong lesson, so month two should be three or four sets a week untimed, focused on building the arrangement correctly. Introduce the selection rubric in month three and the four-minute abandon rule in month four. Full 40-minute DILR sections belong in month five, once both solving and selection are established habits.
How many mocks in a 6-month CAT preparation?
Around 25 to 30 full-length mocks plus 50 to 60 sectional tests, distributed unevenly. One mock per month in months one and two, one per week in months three and four, then two per week through months five and six with a taper in the final week. Each mock needs 120 minutes to attempt and 45 to review, so budget 165 minutes rather than 120 — that time cost is what actually caps how many you can take.
What if I fall behind the 6-month schedule?
Drop topics, protect habits. A missed week of quant topics costs little because topics can be resequenced — shift the schedule right and continue. A missed week of daily reading is expensive because the habit is the entire mechanism, and trying to catch up with three articles a day does not work. Most importantly, never take a mock you will not review: skipping the mock entirely is strictly better than producing a percentile you learn nothing from.
Can I prepare for CAT in 6 months while working?
Yes, on roughly ten hours a week. Put the daily article in the morning before work rather than the evening, because evening reading after a full workday reliably becomes scrolling. Use weekday evenings for one quant topic or a DILR set, and protect Saturday for the full mock plus its review with Sunday for the error-log topics it produces. The margin is thinner than for a full-time candidate, so the Saturday mock matters more — it is both benchmark and deadline.
Should I finish the syllabus before starting mocks?
No, and waiting is one of the more expensive mistakes available. Take your first mock in month one at roughly 60 percent coverage or less, purely to experience the interface and watch a section close at 40 minutes. Ignore the score. Candidates who wait until preparation feels complete discover their sectional-timing problems in the final month, when there is no time left to rebuild habits around them.
Which topics can I skip in a 6-month CAT plan?
Modern maths is the safest thing to compress or drop if time runs short, since permutation, combination and probability form the smallest block in quant and are the slowest to become quick at. Never compress arithmetic, because it compounds into algebra, geometry and data interpretation. And never drop daily reading, which is not a topic at all but the mechanism by which VARC improves — cutting it saves an hour and costs you the section.
What does the last month of a 6-month plan look like?
No new material at all. Month six is two mocks a week driven entirely by your error log, with the selection drill twice weekly for DILR and reading continuing unchanged. RC practice shifts to past papers, which are the most honest difficulty reference available. Taper in the final week to two mocks with none in the last 48 hours, because a poor score two days out teaches nothing actionable and does real damage to how you walk into the centre.
