I am scoring 60-85 percentile in dashcat .But in free mock 1 i got 97 percentile .. what can be my actual cat score ??

Percentile depends heavily on the sample size. Let's say you have a rank of 100 and 1000 people gave the mock then your percentile is 90. But if 10,000 gave the mock and your rank is 100, your percentile is 99. With 2Lakh students appearing for the CAT exam this year, you can expect a significant increase in percentile in the actual examination. No once can exactly predict your score or your percentile. Focus on revising all concepts and formulae. Relax and just have fun out there. Good luck!
