Hey, Deepak

Congratulations for scoring 120 in JEE Main, but considering your Board scores your All India Rank would not be that satisfactory. But no need to worry, there are certain good colleges like Pandit Deendayal Petroleum University, Gandhinagar, LNMIT, Jaipur, Thapar University, Punjab, which consider just the Jee Main Scores, but not the rank. So if you don't hav e too much craze for Government Colleges, then you may happily go for such colleges or else you can appear for improvement and try again in your next attempt.

All The Best for your future.
