i gave cracku 1 free mock and got 92 percentile...but in other paid mocks nearly 50 percentile....plz explain why?

We would recommend you taking mocks from DASHCAT 15-20 as they are closer to the level of actual CAT.
The first few mocks will be slightly harder than actual CAT

I think the reason is that there are more number of people taking free mocks, probably 3000 or so. The paid ones are taken by around 500 people are generally difficult. So even if you score the same marks in both the mocks your percentile will differ.

Now im really worried

Same happened with me as well... I got 83 percentile in free mock but it dropped to around 53 in dash CAT11....

Paid ones are the tough ones
