why are sectional tests of 90 min duration? doesn't make sense, shouldn't they be of 60 min duration?

Hi Anumesh,
Yeah, we understand that the sectional limit for CAT is 60 minutes. However, we wanted to give more time to students when they are solving it as sectional test. It will allow them to spend more time on a particular question. This will help them when they are taking the actual exam. The sectional limit in our mocks is 60 minutes only.
Hope that helps.
