What are the ThinkCAT mock tests?
ThinkCAT's free CAT mocks are real past papers, not invented tests: all 19 complete CAT papers from 2018 to 2025, each in a TCS iON-style interface with a 40-minute timer per section in the VARC, DILR, QA order, the five-state question palette, the on-screen calculator, the TITA keypad and +3/−1 marking (no negative marks on TITA questions). All 19 are free, and you can start without an account; a free sign-in submits the mock. Solutions are step-by-step text; there are no video solutions yet. The official IIM mock opens on iimcat.ac.in with the admit card (12 November in 2025) and needs a CAT login.
