I am scoring around 60-70 percentile in Cracku mock as of now can you tell me how can I improve my score in all three sections and if my percentile remain constant how much I can expect in actual CAT exam?

Focus on sectional mocks

This is what I think about percentiles. Mock - 60-70% , CAT ~ 70 -80% Mock - 70 -80%, CAT ~ 80 - 90% Mock - 80-90%, CAT ~ 90 - 97% Mock - 90+ , CAT ~ 97+ Mock - 95+ CAT ~ 99+ Mock - 98+ , CAT ~ 99.5 Mock - 99+, CAT close to hitting "The" Slot. All these are for consistent scores averaged over at least 10 latest mocks!
