Hello Aspirant.

Assuming you're from general category, so for general category getting your rank under 28,000 would get you into government colleges. Try to keep it below 20,000 to get admission into great colleges among India.

According to the formula then,

Rank=(100-percentile)*8690.10

You need to get atleast 96.5 percentile to get into government colleges(General category).

Best of luck !
