I am not familiar with how the Indian system works. Are other students applying from India applying after grade 10th or 12th equivalent to your school? What was your rank after grade 12th? A 3.85, unless your school has heavy grade deflation and this is known by the colleges you are applying to, will be seen at the low end. At the end of the day, you will first be compared with other applicants from your region in India and then India as a whole. How will you stack up against them?
