After taking the official mock uploaded by IIM Kozhikode I got to know that the pattern of CAT has been changed. It's changed to 28 questions in LRDI and 38 questions in QA. I need suggestions and possible strategies to get a decent score.

First of all. It was a mistake and there is no change in CAT_2k19 pattern. And to get decent score keep working hard and make sure that you don't commit any silly mistake on D-Day. All the keep. Happy Learning. Cheers.....

It is not for sure that is certainly going to happen and I don't think even this happens there is any need of change and certainly you cannot change much now just believe in yourself
