ThinkCAT vs CatMock: Which Low-Cost CAT Mocks Should You Take?

CatMock and ThinkCAT both come up when aspirants look for cheap or free CAT mocks. The difference is what you're paying for. CatMock sells new mocks one at a time. ThinkCAT gives you the real CAT papers on an exam-style screen, with the sectional sprints and topic practice to act on every mock, for one price.

ThinkCAT and CatMock side by side

Real CAT papers on an exam-style screen

ThinkCAT's full mocks are 2018 Slot 1, 2019 Slot 1, 2020 Slots 1 and 2, and all three slots of 2021 to 2025. A score on one of them is a score on a real CAT, so it tells you exactly where you stand.

The screen works like TCS iON: a 40-minute lock on each section in the VARC, DILR, QA order, the five-state question palette, answers that count only after Save & Next, an on-screen TITA keypad, and a basic calculator that works left to right, as CAT's does. The scorecard shows your score, accuracy, attempts, section-wise breakdown and predicted percentile, then every question with its step-by-step solution. Our realism check compares the screen element by element.

More for less: what ₹999 covers

At ₹99 each, 17 CatMock mocks cost ₹1,683, before any sectionals at ₹49 each. On ThinkCAT, all 19 full-length CAT papers are completely free to take. A one-time ₹999 CAT Pro Pass adds:

• 30 timed 40-minute sectional sprints, 10 each for QA, DILR and VARC;
• 3,400+ topic practice questions across the syllabus;
• every past CAT question from 2017 to 2025 by paper and topic, such as CAT 2023 Slot 1 DILR or games and tournaments, each with its official answer and a step-by-step solution.

Daily practice on real CAT questions

ThinkCAT's free 60-day challenge opens a workbook at 6:00 AM IST every day until CAT: about 20 real CAT questions (QA, a full DILR set, an RC passage and VA) to finish in 40 minutes, with a full CAT 2023 section every Sunday. You can solve and see your score as a guest, and sign in for solutions, your streak and the leaderboard.

A six-week plan on ThinkCAT

1. This week: take the free CAT 2024 Slot 1 and Slot 2 papers on ThinkCAT.
2. Through October: the 2021–2023 papers, about two a week, with sectional sprints on your weakest section in between.
3. From November: the 2024 and 2025 papers, the closest to CAT 2026's format.
4. After every mock: log your errors by cause before the next one. The error log template gives you a sheet, and the mock count guide explains the pacing.

Turning one ThinkCAT mock into a week of practice

A mock is worth what you do in the three or four hours after it. Here is how a ThinkCAT mock turns into a week's work.

Read the scorecard by section. Your section scores and attempts show where the marks went. A low DILR score with few attempts is a set-selection problem; a low score with many attempts is an accuracy problem. They need different fixes.

Re-solve before you read solutions. Go back to every question you got wrong or skipped and try it again, untimed. Only then open the step-by-step solution. The questions you can solve with more time are the ones the clock is costing you.

Practise the exact topics the paper exposed. Every ThinkCAT mock is a real CAT paper, and its questions sit in the same topic hubs as ThinkCAT's past-paper archive and practice bank. If a mock shows you losing marks on percentages or arrangements, there are past CAT questions and topic practice questions on that exact topic, and a 40-minute sectional sprint to test the fix against the clock.

Close the loop the next week. Take the next paper and check whether that topic stopped costing marks. One real paper, targeted practice, the next paper: that cycle is how scores climb in the last six weeks. Mocks are free on ThinkCAT, and ₹999 buys the entire practice and sprint ecosystem.

Concept practice, not only past papers

ThinkCAT is more than past papers. Its practice bank holds 3,400+ topic questions written to CAT's pattern across QA, DILR and VARC, organised by concept: percentages, ratios, time and work, functions, logarithms, circles, arrangements, games and tournaments, reading comprehension and the rest. Each topic page pairs those practice questions with the real CAT questions on the same concept, so you learn a method on practice questions and prove it on CAT's own. Formula sheets and the on-screen calculator page sit alongside, all under one pass.
