Hi Amit,

Here you have not mentioned the name of the exam . There are many exam in india like:

1. JEE MAIN
2. BITSAT
3. UPSEEE
4. VITEEE
5. SRMJEEE
6. COMEDK
7. KIITEEE
8. WBJEE
9. MHTCET
10. BCECE

So, here I assume you to be a candidate of JEE MAIN . And if you really secure that much rank then YOU WILL DEFINITELY GET INTO  A REPUTED GOVERNMENT COLLEGE.

BEST WISHES!!!
