Hi, I am able to score more than 95+ile in sectional mock of VARC, but with the same strategy my percentile in Mocks is hardly 85. What can be the possible reasons for this and how do I maintain that above 95+ile in mocks as well.

My advice would be to not look at the percentile instead just look at the scores. The reason for a lower percentile in a mock could be because of more serious candidates. All the serious candidates would take the mocks but might not necessarily take sectionals.
