What is the ThinkCAT Official TCS iON CBT Mock Simulator?
The ThinkCAT CBT Mock Simulator is a pixel-accurate replica of the official TCS iON computer-based testing engine utilized by the Indian Institutes of Management (IIM) for the Common Admission Test. The simulator delivers an authentic 120-minute timed testing environment with strict, automated 40-minute sectional locks transitioning chronologically through Verbal Ability & Reading Comprehension (VARC), Data Interpretation & Logical Reasoning (DILR), and Quantitative Aptitude (QA). Candidates interact with the real on-screen scientific calculator, standard font-scaling controls, and the official 5-state TCS iON question palette: Not Visited (Gray), Not Answered (Red), Answered (Green), Marked for Review (Purple), and Answered & Marked for Review (Purple with Green Dot). Post-exam diagnostic reports calculate raw scores (+3 for correct, -1 for wrong MCQs, 0 for TITA) and project calibrated national percentile curves benchmarked against verified convenor response distributions.

Are these mock exams official past CAT papers?
Yes. Every mock test in the ThinkCAT series comprises authentic, unedited questions from official CAT exams released by conducting IIM convenors, verified against candidate response sheets.

No. In strict accordance with official IIM convenor guidelines, sections are locked to exactly 40 minutes each. You cannot jump ahead or return to prior sections once their timer expires.
