Hey Suresh,
Admissions in government colleges are quite competitive because of the vast patient exposure. Your target for score should be 600+. Also it depends on the quota you are applying in. Study Hard and aim for the highest possible score. All the very best!
In case, yor query is regarding 85% or state quota then its cut off varies state wise or if you talk about AIQ then the closing rank in previous year for MBBS general category was 8317 so according to this much rank the safest score to get should be approx 560.
Good Luck!!!
