Written for the CAT paper specifically.
Overlearning in CAT Prep: When More Practice Stops Working
A 218-student trial found that drilling material you have already mastered boosts recall for about a week, then the advantage collapses - and in the second experiment, studying more material to a lesser degree actually beat overlearning less material, at every retest. CAT prep runs for months, not a week.
CAT Vocabulary List: 500 Words, and Why Lists Alone Fail
A real list of CAT-relevant advanced words, plus the honest research on why memorising an isolated list transfers weakly to VARC - CAT tests usage in context, not synonym recall - and what actually builds working vocabulary: retrieval, not scanning.
CAT Mock Analysis Excel Template: What It Can and Cannot Do
A spreadsheet can log a CAT mock score in ten seconds. It cannot, without real maintenance, tell you which mock is due for its next revision pass, flag a section that has silently plateaued, or keep a session linked to the specific mock it was about. Here is the column schema to use if you build one anyway, and the three specific jobs where it breaks.
Why Mock Scores Plateau: 10 Weeks Flat in My Own Log
My overall mock score averaged 61.8, then 59.8, then 62.0 across three consecutive blocks of five - ten weeks of nothing. Underneath it VARC was gaining 7.8 marks and Quant was losing 3.4. The plateau was two real trends cancelling, which is also what the learning-curve research says a plateau usually is.
Study Tracker Excel Template vs App: Where Sheets Break
A spreadsheet is genuinely the right tool for a short, low-volume tracking need, and it is the wrong one for a twelve-month exam cycle. Here are the five specific places mine broke, measured against my own log of 340 sessions and 20 mocks - plus the column schema to use if you build one anyway.
The 1-3-7 Revision Rule vs What Spaced Repetition Shows
"Revise after 1 day, 3 days and 7 days" is repeated across Indian exam-prep content with no cited source, and I could not find one either. Here is what the real spaced-repetition evidence says about a schedule that stops at day 7, and where it happens to be right anyway.
How Many Hours to Study for CAT? 20 Mocks, One Honest Answer
I logged 335 hours and sat 20 CAT mocks in the same three months, so I can check the question directly instead of guessing at it. The relationship is much weaker than the advice implies: elapsed preparation time explains 14% of the variation in any single mock, and the days available between two mocks predict the score change at r = 0.04, which is nothing.
How to Build a Study Habit: 66 Days Is a Median, Not a Law
The "66 days to form a habit" number comes from 39 people drinking water and doing sit-ups, and the actual range was 18 to 254 days. Here is what that study really found, what it says about a study streak, and why the same paper is the best argument for not punishing a missed day.
Spaced Repetition for CAT Revision: What 317 Experiments Say
The meta-analysis behind spaced repetition covers 317 experiments and 14,811 people, and it says less about revising a CAT mock than every study-tips post assumes. Here is what it does say, what it does not, and the schedule I actually run.
Sleep Before Exam: The Night Before Barely Matters
MIT researchers put Fitbits on 88 students for a full semester. Sleep the night before a midterm predicted nothing. Sleep across the month the content was taught predicted grades. Here is what that changes about CAT prep, and what my own log cannot tell you.
Overconfidence in Exam Prep: The 14-Point Blind Spot
Across 310 students, the average first-exam prediction was 85% and the average actual score was 71%. The weakest quarter were out by 32 points. Here is why the gap exists, the one intervention that closed it, and the study that found overconfidence also helps.
Mock Percentile vs Actual CAT Percentile: My 18 Papers
A 54 and a 96 both returned the 90th percentile in my own mock log. Six pairs invert outright. Which is why "mocks inflate your percentile by 3-8 points" cannot be true in either direction - and what to track instead.
How to Track Study Hours: A Method, and Its Real Limits
Log one row per session, at the moment it ends, with minutes that were measured rather than remembered. That much is worth doing. What tracking will not do is raise a score on its own - in my own log, elapsed prep time explains 14% of the variance in my mock results and my weakest section did not move at all.
Interleaving Quant Practice: 61% vs 38% in One RCT
A pre-registered randomised trial across 54 maths classes found mixed practice beat topic-wise practice 61% to 38% on a delayed test. My own log shows why that matters for CAT: the section I drilled topic-wise improved nine marks, and the section that needs selection improved two.
How Many CAT Mocks Should I Take? I Took 20 in 90 Days
The honest answer is 25 to 35 across a full cycle, and the count is the least important part of it. I took 20 in 90 days, seven of them within 48 hours of the previous one, and those seven taught me nothing at all.
How Many Hours a Day Should You Study for CAT? I Logged 335
My weekly goal was 1,260 minutes and my average active day is 149 minutes, which needs 8.5 days a week to hit. Here is the arithmetic that broke my own target, what 335 logged hours actually bought, and why the hours literature is far shakier than the 10,000-hour story suggests.
Error Log for CAT Mocks: Eight Categories, Seven Passes
An error log is one row per mistake classified by why it happened, not a list of question numbers. Here is the eight-category taxonomy, the row nobody logs, and how the log becomes the actual content of every revision pass from R1 to R7 - instead of redoing a paper you already know the answers to.
Exam Anxiety and Mock Scores: I Scored 96, Then 40
Two days apart, my best mock and my worst. The anxiety research explains less of that gap than you would expect - about 12% of variance at best - and the arithmetic of two outliers explains a lot more. What to check before you diagnose yourself.
Deliberate Practice for CAT: What 88 Studies Actually Say
The "quality beats quantity" claim has a real evidence base and a much smaller effect than the popular version admits: 12% of performance variance overall, 4% in education. Here is what survives contact with the meta-analysis, and what my own DILR log says about practising a section for three months and moving two marks.
CAT Study Plan for 3 Months vs 6 Months, Week by Week
CAT 2026 falls on 29 November, which makes a 13-week plan the one most people are actually running. Here are both timelines laid out week by week, the honest list of what compression costs you, and the one section that suffers most when you cut.
CAT Slot Normalization: How Raw Scores Become Percentiles
CAT runs three slots on exam day with different question sets, so a raw score means nothing until it is normalized against the people who sat the same slot. Here is why that step exists, how equating works in principle, and the plain fact that IIMs have never published the exact formula they use.
CAT Negative Marking Strategy: The Real Expected-Value Math
CAT's +3/-1 marking means a genuinely blind guess on a standard four-option MCQ has an expected value of exactly zero - not the small positive edge NEET's +4/-1 gives you. Eliminate even one option and the calculus flips hard in your favour. Here is the arithmetic worked properly, section by section.
Active Recall vs Rereading: What 200 Students Showed
In a 2011 Science experiment, 101 of 120 students learned more from retrieval practice than from an elaborative study method - and only 30 of them expected to. That gap between what works and what feels like it works is the whole reason people reread.
Best Time to Study Morning or Night: What 3.4M Logins Say
There is no universal best hour, and the largest datasets on this question disagree about which direction the effect even runs. Here is what four studies actually found, including the one whose own prediction was refuted, and a three-week test you can run on your own log instead.
My 20 CAT Mocks: 41 to 91, With Every Crash Left In
Three months of real mock scores, section by section, including the mock where I scored 40 two days after scoring 96. Not a success story - a log of what the aggregate number hid.
CAT Preparation Without Coaching: What I Built to Replace It
I haven't enrolled in a single coaching institute for CAT. What I did instead was write a month-by-month plan, buy standalone mock series, and build my own tracker when nothing on the market did what I needed. 340 logged sessions later, here is what actually replaced coaching and what didn't.
CAT Selection Process: WAT, GD, and Personal Interview
I haven't sat a WAT-GD-PI round myself - my CAT is in November, so any interview process is still months off if it happens at all. What follows is what the process actually involves and how I'm planning to prepare for it, not a memoir of a round I haven't lived yet.
How to Analyse CAT Mocks: 5 Steps, One 96-40-94 Week
On 29 July I scored 96. On 30 July, 40. On 1 August, 94. Same person, four days, three mocks. Here is the actual analysis framework, worked through that stretch and one sectional test, rather than asserted in the abstract.
CAT Preparation for Non-Engineers: What a B.Tech Doesn't Buy
I have an engineering degree from BITS Pilani, so I can't speak firsthand to the non-engineer experience. What I can tell you is which section that degree actually helped with, and which one it did nothing for at all - my own DILR score moved two marks in three months of deliberate practice.
CAT Exam Time Management: What a 96-to-40 Crash Cost Me
On 29 July I scored 96. On 30 July, same knowledge, same person, I scored 40 - with 2 marks in DILR. The gap was not ability. It was 40 seconds spent staying on a set I should have abandoned. Here is what that mock taught me about time management.
CAT Reading Comprehension: The 6 Question Types It Tests
On 28 June my VARC score was 5, at the 15th percentile. The question that broke it: a passage about Descartes, an answer option that said "Descartes and other philosophers," and I picked it. Here is the inference-vs-overreach line that question sits on, and the other five RC question types CAT actually tests.
CAT Prep While Working Full-Time: 21 Hours in 59-Minute Bits
My weekly goal is 1,260 minutes - 21 hours - and my average session is 59 minutes, not the 2-hour blocks I imagined when I set the goal. Here is what working full-time actually does to a study schedule, in my own logged numbers.
CAT Cutoffs for Top IIMs: One Weak Section Filters You Out
A strong overall percentile can still get you filtered out by one weak section. My own VARC scores swung from the 12th percentile to the 92nd across five mocks I logged this quarter - and IIM Ahmedabad's own January 2026 policy document, read directly rather than via a coaching-site round-up, sets the real bar well above what most of those round-ups print.
Best CAT Preparation Books: The 3 of 6 I Finished
I own six CAT prep books. I logged real hours against three of them and the other three sat closed after week two. Here is which ones earned their shelf space, checked against my own subject-tagged session log.
CAT Percentile vs Score: What 45 Real Mock Results Show
Percentile is not a function of score, and here is the proof: 45 real score-to-percentile pairs from 15 mocks, including a DILR score of 15 that landed at the 65th, 76th and 90th percentile on three different papers.
CAT 2026 Exam Pattern and Syllabus: The Non-MCQ Trap
The section-wise structure, timing, and marking scheme I keep pinned above my desk, plus the one rule about Non-MCQs that cost me marks on an early mock before I actually read it properly.
Mental Math for CAT: Why Tables Stop at 25, Not 12
Tables to 25, squares to 30, cubes to 20, and a handful of fraction-percent conversions - not because a list says so, but because the algebra behind each one shows exactly where the boundary should sit and why.
CAT Exam Day Tips: The Routine I Ran Before 20 Mocks
I haven't sat the real CAT yet - mine is in November - but I've run this exact pregame for 20-plus mocks, including the one where I scored 96 and the one two days later where I scored 40. Here is the routine, and the mock-day failure that taught me why it matters.
CAT DILR Practice: 75% Accuracy at the 35th Percentile
My own DILR score has run from 2 to 30 across 23 mocks - the same section, the same person, a 3.5-month window. One sectional note explains more of that gap than any generic tip does: I could have doubled a score just by attempting more of what I already knew how to solve.
CAT Quant Shortcuts: 8 Techniques and Why Each One Works
Eight calculation techniques for CAT Quant, each with the algebra behind it and where it actually appears in the paper. Understanding why a shortcut works is what makes it survive exam pressure.
CAT VARC Preparation: A 3-to-39 Score Range Across 23 Mocks
My VARC score has run from 3 to 39 across 23 mocks - a 13x swing in the same section. A note I wrote myself after one sectional explains most of the gap: "could have gotten 35 though - always look carefully and eliminate extreme options."
CAT 2026 Study Plan: 340 Sessions and 23 Mocks So Far
My CAT 2026 exam is on 29 November. Here is the actual month-by-month shape of my prep so far - 340 sessions, 23 mocks, one four-day stretch that went 96, 40, 94 - and what changes for the 13 weeks left.
Study practice
Not exam-specific - habits, mocks and consistency, which carry across all three.
Study Progress Tracker: Google Sheets Template vs App
Three real Google Sheets formulas people actually use to track study time - SUMIFS for weekly totals, conditional formatting for a manual heatmap, a pivot table for subject breakdown - and the specific point at which each one needs upkeep a dedicated app does not.
How to Focus While Studying: What the Research Says
Interrupting a long study session with short, frequent self-tests cuts reported mind-wandering roughly in half and improves recall, in a controlled study of 80 students learning from video lectures. What that finding actually supports for exam prep, and what it does not.
Best Study Tracker Apps for Competitive Exams, Compared
There is no single best study tracker - there are three genuinely different categories, and each one can represent some data and structurally cannot represent the rest. A fair comparison of generic habit trackers, spreadsheets, and exam-specific tools, by what each can and cannot store, not by marketing claims.
Best Time to Take a Mock Test: Match Your Exam Slot
This is not "when is the best time to study" - it is a narrower, testable claim: schedule your mocks at the same clock hour as your actual exam slot. The direct experiment that would prove this has never been run. Here is the real evidence that exists next to it, and why the recommendation still holds up anyway.
Procrastination and Exam Prep: What 691 Correlations Show
Procrastination correlates with academic performance almost as strongly as conscientiousness does, and barely at all with intelligence. Piers Steel's 2007 meta-analysis pooled 216 studies and 691 correlations - here is what it actually found about why people delay, and what changes it, that has nothing to do with habit streaks.
Why Studying With Friends Beats Studying Alone for CAT Prep
My own average session mood is 3.60 out of 5 - not high, mostly just 'showed up anyway.' That's exactly the kind of day solo willpower fails and a friend who can see your log doesn't care that you weren't excited about it.
Study Timer vs Pomodoro: My 340 Sessions Average 59 Minutes
My own 340 logged sessions average 59 minutes - well past a Pomodoro interval - and my longest single session ran 190 minutes. That gap is the actual argument for when a fixed 25-minute timer helps CAT prep and when it gets in the way.
How to Build a Study Streak: 5 Habits From 135 Active Days
340 sessions, 135 active days, one 190-minute outlier against a 59-minute average - and a streak that has broken more than once. Here is what my own Karma Yogi data says actually keeps a study habit alive.
