Hi priyanshu, 

With this rank it will be difficult to get a government engineering college.  But you should try in counselling if you will not get a seat in the counselling then you will have three options one is to drop and prepare for jee next year. Second is to get a paying seat in government engineering college but it will be much costlier thats why it does not seems to be good option. Third is to get admission in a good private engineering college and have can there. 

You just need to have a passion for cs and try to gain as much knowledge as you can have. 

At the end knowledge matters more than college name. 

For any other information you can ask us.
