i am getting around 30-40 in mocks consistently how much can i expect in the real exam - marks and percentile

It is a subjective question but u can still expect around 10-15 more marks that would result into around 90-95 percentile, it's better you work hard we still have 19-20 days and we can reach 99 percentile

it depends whic section u arre scoring most if u just say get 30 in varc (my case)its already saturated to a lot extent dont expect more from that section
