What Ninetynine is
Ninetynine is an online practice platform for CAT, the entrance exam for the IIMs and most Indian MBA programmes. It is built on the 24 CAT papers from 2017 to 2025 (1,830 questions). The free layer of this site publishes every one of those questions with CAT's official answer, its topic, and a worked solution where one has been written and checked. Signed-in students get unlimited mocks cut from the real papers, a similar question to practise after each PYQ, and analysis of every attempt, for a one-time payment of ₹99.
